Spectroscopic signatures of halogens in clathrate hydrate cages. 1. Bromine.
We report the first UV-vis spectroscopic study of bromine molecules confined in clathrate hydrate cages. Bromine in its natural hydrate occupies 51262 and 51263 lattice cavities. Bromine also can beExpand

Polymorphism in Br2 clathrate hydrates.
The structure and composition of bromine clathrate hydrate has been controversial for more than 170 years due to the large variation of its observed stoichiometries. Several different crystalExpand

Vibrational dissipation and dephasing of I2 (v = 1-19) in solid Kr.
Time- and frequency-resolved coherent anti-Stokes Raman scattering is used to carry out systematic measurements of vibrational dephasing on I2 (v = 1-19) isolated in solid Kr, as a function ofExpand

Dynamical interrogation of the hydration cage of bromine in single crystal clathrate hydrates versus water.
We report transient grating measurements carried out on single crystals of bromine clathrate hydrates and on bromine dissolved in water. In all cases, excitation into the B-state of Br2 leads toExpand

Quenched by ice: transient grating measurements of vibronic dynamics in bromine-doped ice.
In both water and in ice, the absorption spectra of bromine are dramatically broadened and blueshifted, and all fluorescence is quenched. Time resolved, electronically resonant transient gratingExpand

Vibronic dynamics of I(2) trapped in amorphous ice: coherent following of cage relaxation.
Four-wave mixing measurements are carried out on I(2)-doped ice, prepared by quench condensing the premixed vapor at 128 K. Coherent vibrational dynamics is observed in two distinct ensembles. TheExpand

Quantum tomography of a molecular bond in ice.
We present the moving picture of a molecular bond, in phase-space, in real-time, at resolution limited by quantum uncertainty. The images are tomographically reconstructed Wigner distributionExpand

EPR spectroscopy of the radical–molecular complex NH2–HF formed in low temperature chemical reaction of fluorine atoms with NH3 molecules trapped in solid argon
Abstract Chemical reactions of F atoms with NH 3 molecules in a solid argon matrix were studied with electron paramagnetic resonance (EPR) spectroscopy. Fluorine atoms were generated by UV photolysisExpand

High-resolution electron spin resonance spectroscopy of XeF* in solid argon. The hyperfine structure constants as a probe of relativistic effects in the chemical bonding properties of a heavy noble
Xenon fluoride radicals were generated by solid-state chemical reactions of mobile fluorine atoms with xenon atoms trapped in Ar matrix. Highly resolved electron spin resonance spectra of XeF* wereExpand
