Helium nanodroplet isolation spectroscopy in an undergraduate teaching laboratory
نویسندگان
چکیده
A home-built helium nanodroplet isolation spectrometer has been utilized by undergraduate students in course-based experiments to investigate the rovibrational dynamics of small molecules. Helium nanodroplets are a versatile medium that simplifies spectroscopy embedded molecules owing their low temperature (0.4 K) and weakly interacting nature. In infrared spectral region, this often results number rotationally resolved lines can be observed analyzed within several lab periods. We demonstrate advantages using well-established technique an upper-level chemistry course for which laser solvated 13C-labelled formic acid was investigated first time.

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 کاملA new sensitive detection scheme for helium nanodroplet isolation spectroscopy: application to benzene.
A new method is presented for recording excitation spectra of molecules embedded in helium nanodroplets. The method relies on the complete evaporation of the droplets following excitation of a dissolved molecule and the subsequent detection of the remaining unsolvated molecule by mass spectrometry. The technique has been successfully applied to record the S1 1B(2u) <-- S0 1A(1g) transition in b...
