Rotationally resolved infrared spectra are reported for the X-HCN (X = Cl, Br, I) binary complexes solvated in helium nanodroplets. These results are directly compared with those obtained previously for the corresponding X-HF complexes [J. M. Merritt, J. Küpper and R. E. Miller, Phys. Chem. Chem. Phys., 2005, 7, 67]. For bromine and iodine atoms complexed with HCN, two linear structures are observed and assigned to the (2)Sigma(1/2) and (2)Pi(3/2) ground electronic states of the nitrogen and… 
Spectroscopy of free radicals and radical containing entrance-channel complexes in superfluid helium nanodroplets
The spectroscopy of free radicals and of radical containing entrance-channel complexes embedded in superfluid helium nanodroplets is reviewed. The collection of dopants inside individual droplets
Infrared Stark and Zeeman spectroscopy of OH-CO: The entrance channel complex along the OH + CO → trans-HOCO reaction pathway.
Inhomogeneous line broadening in the zero-field spectrum is modeled with an effective Hamiltonian approach that aims to account for the anisotropic molecule-helium interaction potential that arises as the OH-CO complex is displaced from the center of the droplet.
Analytical potential energy surface for the reaction with intermediate complexes NH3 + Cl → NH2 + HCl: Application to the kinetics study
We present for the first time an analytical potential energy surface (PES) for the reaction of hydrogen abstraction from ammonia by a chlorine atom. It has a very complicated shape with various
Infrared spectroscopy in superfluid helium droplets
ABSTRACT For more than two decades, encapsulation in superfluid helium nanodroplets has served as a reliable technique for probing the structure and dynamics of molecules and clusters at a low
Can a gas phase contact ion pair containing a hydrocarbon carbocation be formed in the ground state?
So far, no conclusive evidence of a ground-state contact ion-pair containing a hydrocarbon carbocation has been given in the gas phase. Due to the very high stability of the 1,2:4,5-dibenzotropylium
Helium Droplets: An Apparatus to Study Ultra Cold Chemistry
A new pulsed helium nano droplets machine has been constructed. The droplets were generated by expansion of the pure helium through the cryogenic valve attached to a closed-cycle cryostat. The mean
Multiscale theory of finite-size Bose systems: Implications for collective and single-particle excitations
Boson droplets (i.e., dense assemblies of bosons at low temperature) are shown to mask a significant amount of single-particle behavior and to manifest collective, droplet-wide excitations. To


Entrance channel X-HF (X = Cl, Br and I) complexes studied by high-resolution infrared laser spectroscopy in helium nanodroplets.
Rotationally resolved infrared spectra are reported for halogen atom-HF free radical complexes formed in helium nanodroplets, confirming that the observed species have 2Pi3/2 ground electronic states, consistent with the linear hydrogen bound structures predicted from theory.
Infrared laser spectroscopy of the CH3-HCN radical complex stabilized in helium nanodroplets.
Deuteration of the methyl radical was used to detune these levels from resonance, increasing the lifetime of the complex by a factor of 2.2, and ab initio calculations for the energies and molecular parameters of the stationary points on the CN+CH4 --> HCN+CH3 potential-energy surface are presented.
High-resolution spectroscopy of NO in helium droplets: a prototype for open shell molecular interactions in a quantum solvent.
The high-resolution infrared spectrum of the radical NO in the (2)Pi(1/2) state in superfluid helium nanodroplets is measured and the hyperfine interaction is found to be unaffected by the He solvation.
Infrared laser spectroscopy of CH3...HF in helium nanodroplets: The exit-channel complex of the F + CH4 reaction.
The results suggest that fast relaxation in the former case results from near-resonant intermolecular vibration-vibration (V-V) energy transfer.
Polar isomer of formic acid dimers formed in helium nanodroplets.
The infrared spectrum of formic acid dimers in helium nanodroplets has been observed corresponding to excitation of the "free" OH and CH stretches. The experimental results are consistent with a
The Growth of HF Polymers in Helium Nanodroplets: Probing the Barriers to Ring Insertion
We report the first experimental observation of (HF) n (n = 4,5,6) clusters, grown in helium nanodroplets. The structures of these complexes are determined from infrared laser spectroscopy, recorded
Ab initio treatment of the chemical reaction precursor complex Cl(2P)-HF. 2. Bound states and infrared spectrum.
Bound energy levels and properties of the Cl(2P)-HF complex were obtained from full three-dimensional (3D) calculations, with the use of the ab initio computed diabatic potential surfaces from the
Spectroscopy and dynamics of hydride radical van der Waals complexes
Spectroscopic and theoretical studies of hydride radical–rare gas atom complexes (Rg–HX) are reviewed. This family of van der Waals molecules is of interest as they can be used to explore the
Infrared spectroscopy and structures of Arn–HF in liquid helium nanodroplets
Infrared spectra are reported for Arn–HF complexes up to the closing of the first solvent shell. These complexes were grown in superfluid helium droplets, leading to the formation of multiple isomers
