Vibrational analysis of isopropyl nitrate and isobutyl nitrate.
TLDR
Infrared intensities of isopropyl nitrate are consistent with the twisted geometry, demonstrating that this conformer is favored in solution and providing evidence that the condensed phase, ground-state molecular structure of isobutyl nitrates is of Cs symmetry. Expand
Investigation of terahertz vibration-rotation tunneling spectra for the water octamer.
TLDR
A combined theoretical and experimental study of the water octamer-h16 finds transitions appear as singlets, consistent with the instanton paths, which involve the breakage of two hydrogen-bonds and thus give tunneling splittings below experimental resolution. Expand
Infrared Cavity Ringdown Spectroscopy of Jet-Cooled Nucleotide Base Clusters and Water Complexes
We present the first direct infrared absorption measurements of gas phase nucleotide base clusters and complexes with water. Spectra in the NH stretching region indicate the presence of severalExpand
A long path length pulsed slit valve appropriate for high temperature operation: Infrared spectroscopy of jet-cooled large water clusters and nucleotide bases
We report the design and performance of a pulsed slit valve for generation of supersonically cooled species in a long path length planar expansion. Utilizing three commercial solenoids drivenExpand
Water pentamer: characterization of the torsional-puckering manifold by terahertz VRT spectroscopy.
TLDR
It is concluded, through careful analysis of five new (D2O)5 bands, that at least three torsional-puckering manifolds have been probed and that the lowest-energy manifold is highly compacted. Expand
Infrared laser spectroscopy of uracil in a pulsed slit jet
A new high‐temperature pulsed slit jet source has enabled the first observation of a rotationally resolved vibrational spectrum of a nucleotide base. The spectrum, centered at 1703.888 cm−1, has beenExpand
QUANTITATIVE CHARACTERIZATION OF THE WATER TRIMER TORSIONAL MANIFOLD BY TERAHERTZ LASER SPECTROSCOPY AND THEORETICAL ANALYSIS. II. (H2O)3
We report the measurement of two new (H2O)3 bands by terahertz laser vibration–rotation–tunneling (VRT) spectroscopy. Both bands have been assigned to torsional (“pseudorotational”) transitions andExpand
Vibrational analysis of n-butyl, isobutyl, sec-butyl and tert-butyl nitrite.
TLDR
Evidence is provided that suggests that the relative number of cis conformers to trans conformers decreases as the alpha-carbon branching increases, and among the several predicted geometries of these compounds, the cis-trans geometry was calculated to be the most stable conformer of n-butyl and isobutyl nitrite.

Absolute Resonance Raman Intensity Analysis of Isopropyl Nitrate in the Condensed Phase
The first resonance Raman spectra of isopropyl nitrate (IPN) are reported. Absolute resonance Raman scattering cross-sections for IPN dissolved in cyclohexane and acetonitrile are measured atExpand
Cold-surface photochemistry of primary and tertiary alkyl nitrites.
TLDR
The results point to cold surface processing of alkyl nitrites as a potential environmental source of nitrous oxide and the reaction rates for cis and trans conformer decay were found to be significantly different. Expand
