High Resolution IR Study of the Coriolis Coupling between ν3and ν9in Methylene Chloride

High Resolution Spectra and Rotational Analysis of the 2ν8, ν2+ ν8, and 2ν2Bands in Methylene Chloride

“…We most probable candidate. Simulations and fits have been calculated the expected rotational constants for n 2 / n 8 from performed, fixing the rotational constants of the perturber to n 8 (7) and 2n 2 molecular parameters (this work) and found values determined by the three fundamental modes (high that the expected values for the B and C rotational constants resolution analyses are available for all three (7,8) and differed significantly from those resulting from our analysis.…”

“…The observable bands in the 2450-2900 cm 01 range are 3.2.1. The 2n 8 overtone. The 2n 8 overtone band of the 2n 8 overtone, the combination band n 2 / n 8 , and the overtone 2n 2 , with intensities ranging from very weak (2n 8 ) CH 35 2 Cl 2 of symmetry A 1 appears as a perfectly unperturbed B-type band ( Fig.…”

“…The present work deals with high resolution (0.0044 cm 01 ) infrared spectra and a full rotational analysis of the 2n 8 , n 2 / n 8 , and 2n 2 bands of CH 35 2 Cl 2 . Possible rotational Methylene chloride is a well known solvent, with applicaperturbations will be discussed in terms of macroscopic spections in solvent decaffeination (1) and in pharmaceutic and tral features, line-by-line analysis, and vibrational isotopic electronic industries.…”

“…Consequently a full rotational line-by-line analysis of the spectrum was considered to be prohibitive and a simulation of the 2n 8 / n 4 -n 4 band was performed, using the n 4 molecular parameters of Ref. (13), a band origin of n 4 Å 283.189(2) cm 01 (17), and assuming changes in the rotational constants similar to those of the overtone 2n 8 Table 3. around K a Å 10.…”

“…The Dopplerwidth at room temperature is about 0.0036 cm 01 . The spectrum was califor both isotopic species (8,9). Raman spectra are reported in (10).…”
