High-resolution spectroscopic studies of carbon-containing species
… From the fundamental side, high-resolution rovibrational spectroscopy allows molecular constants to be determined and provides evidence of theoretical assumptions. Work to this end was performed using cavity-ringdown spectroscopy and either a gas phase or supercritical fluid supersonic …

Quartic Force Fields for Electronically Excited States of Interstellar Molecules
<p>Theoretical chemistry has advanced to the point where spectroscopic data can be produced that is directly comparable to high-accuracy experimental results. Quartic force field (QFFs) methods are one of the most efficient means of generating this data and have even shown spectroscopic accuracy …
