Helium Nanodroplet Isolation Spectroscopy in an Undergraduate Teaching Laboratory
Paul Raston
Abstract:<div><p>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 well known to simplify the spectroscopy of
embedded molecules owing to their low temperature (0.4 K) and weakly
interacting nature. In the infrared spectral region, this results in a small
number of rotationally resolved lines that can often be collected and analyzed
in several lab… Show more
