Abstract

Wir zeigen Simulationen und Anpassung der feldfreien und Stark optischen Spektren verschiedener Molekülarten in der Gasphase und in Heliumtröpfchen, die in der Literatur verfügbar sind, unter V erwendung eines Simulationsprogrammpakets PGOPHER. Weiterhin analysieren wir die relativen spektralen Breiten der feldfreien linearen und symmetrischen Top-Rotoren und zeigen eine Skalierungsbeziehung zwischen den relativen Spektralbreiten und den Renormalisierungsverhältnissen der Rotationskonstanten.

We present simulations and fits of the field-free and Stark optical spectra of various types of molecules in the gas phase and in helium droplets that are available in the literature using a simulation package PGOPHER. Furthermore, we analyze the relative spectral widths of field free linear and symmetric top rotors and present a scaling relationship between the relative spectral widths and the renormalization ratios of the rotational constants.
