High‐resolution stimulated Raman spectroscopy and analysis of line positions and assignments for the ν₂ and ν₃ bands of ¹³C₂H₄

Abstract

D 2h symmetry (developed in Dijon) and a program suite called D 2h TDS (now part of the XTDS/SPVIEW spectroscopic software) were proposed to analyze and calculate the high-resolution spectra. A total of 103 and 51 lines corresponding to 2 and 3 Raman active modes have been assigned and fitted in wavenumber with a global root mean square deviation of 0.54 10 3 and 0.36 10 3 cm 1 , respectively. Due to the fact that the Raman scattering effect is weak, we did not perform in this contribution the line intensities analysis.

“…Alkadrou et al carried out high‐resolution stimulated Raman spectroscopy and analysis of line positions and assignments for the ν 2 and ν 3 bands of 13 C 2 H 4 . The spectra were recorded at two temperatures (145 and 296 K) based on the quasi continuous‐wave (cw) stimulated Raman spectrometer at the Instituto de Estructura de la Materia IEM‐CSIC in Madrid …”
