Communication: Helium nanodroplet isolation and rovibrational spectroscopy of hydroxymethylene.
Hydroxymethylene (HCOH) and its d1-isotopologue (HCOD) are isolated in low temperature helium nanodroplets following pyrolysis of glyoxylic acid. Transitions identified in the infrared spectrum are assigned exclusively to the trans-conformation based on previously reported anharmonic frequency computations [P. R. Schreiner, H. P. Reisenauer, F. C. Pickard, A. C. Simmonett, W. D. Allen, E. Mátyu...
متن کاملHelium nanodroplet isolation rovibrational spectroscopy: Methods and recent results
In this article, recent developments in helium nanodroplet isolation ~HENDI! spectroscopy are reviewed, with an emphasis on the infrared region of the spectrum. We discuss how molecular beam spectroscopy and matrix isolation spectroscopy can be usefully combined into a method that provides a unique tool to tackle physical and chemical problems which had been outside our experimental possibiliti...
متن کاملHelium nanodroplet isolation spectroscopy of perylene and its complexes with oxygen.
Helium nanodroplet isolation ~HENDI! is an established and unique way to carry out spectroscopic investigations of a broad range of molecular species. The very low temperature of and the very weak interaction with the helium matrix allow for the observation of significantly simplified spectra. As the superfluid environment is similar to the gas phase, frequently rotational structure can be obse...
متن کاملHelium nanodroplet isolation spectroscopy and ab initio calculations of HO3-(O2)n clusters.
HO3-(O2)n clusters are formed by the sequential addition of the hydroxyl radical and O2 molecules to superfluid helium nanodroplets. IR laser spectroscopy in the fundamental OH stretching region reveals the presence of several bands assigned to species as large as n=4. Detailed ab initio calculations are carried out for multiple isomers of cis- and trans-HO3-O2, corresponding to either hydrogen...
متن کاملFirst overtone helium nanodroplet isolation spectroscopy of molecules bearing the acetylenic CH chromophore
High-resolution helium nanodroplet isolation spectra of the first overtone ~2n1) of the acetylenic stretch of several substituted acetylenes ~RC[C–H! at T50.38 K, have been observed for the first time. A tunable 1.5 mm laser is coupled, using a power buildup cavity, to a beam of He droplets seeded with the molecule to be studied. Absorption spectra are recorded by monitoring the beam depletion ...
