Abstract:
For the first time, rotational constants along with centrifugal distortion constants have been determined for OThS and OCeS. The rotational spectra of these molecules and, in each case, one other isotopologue (OTh34S and O142CeS) were produced utilizing a laser ablation sourcing technique incorporated into a chirped-pulse Fourier transform microwave spectrometer operating in the 8 to 18 GHz region of the electromagnetic spectrum. The bent structures determined are in very good agreement with theoretical calculations. Comparisons between atomic coordinates, bond lengths and angles, as well as the inertial defect are discussed.

Raman Spectroscopy Instrumentation: Overview
The monochromatic laser source, typically using visible or near-infrared radiation, generates a highly focused beam of light. This light interacts with the molecules of the sample, scattering some of the light. Liquid and gaseous samples are usually tested in ordinary glass capillaries, while solids can be analyzed as powders packed in capillaries or as potassium...
