Revisiting N2-N2 collisional linewidth models for S-branch rotational Raman scattering

Toward Gas-Phase Thermometry Using Pure-Rotational Impulsive Stimulated Raman Scattering Spectroscopy with a Low-Energy Femtosecond Oscillator

“…Moreover, the long-time rotational revivals were shown to be affected by pressure-dependent energy transfer effects that alter the initial rotational coherence [33,34] and consequently the derived rotational spectral intensities. In this case, the use of experimental data to obtain information on the sample pressure or temperature requires apposite models whose development and suitability are still under debate [33,35]. Therefore, measurements at short delay times have significance since they represent an instantaneous picture of the rotational coherence created by the pump pulse.…”

Energy efficiency of N2 vibrational excitation in the spark-and-glow phases of a long-pulse air discharge at atmospheric pressure

“…The rotational temperature T r , the first-level vibrational temperature T v01 and the vibrational temperature T v1v were used to characterise the rovibrational distributions of N 2 (X, v = 0, 1) and N 2 (X, v = 1, v > 1), respectively. Besides, the Raman line width was determined by the modified exponential gap model, and the fitting parameters are taken from the work by Linne et al [24].…”
