High-resolution Fourier transform spectrum of H2S in the region of 8500–8900cm−1

High-resolution rotational analysis of HDS: 2ν3, ν2+2ν3, 3ν3, and ν2+3ν3 bands

“…The present work is devoted to the high-resolution Fourier-transform spectroscopy study of HDS in the infrared region, continuing our previous studies [9,10] on the high-resolution ro-vibrational spectroscopy of the hydrogen sulfide molecule (H 2 S/HDS/D 2 S). The experimental details are presented in Section 2.…”

“…In the last few decades, the absorption spectra of H 2 S have been studied extensively, with microwave [2][3][4][5][6], Fourier-transform infra-red [7][8][9][10][11][12][13], and intracavity laser absorption spectroscopy at near-IR and visible region [14][15][16][17][18][19][20][21]. But for the deuterated sample, there are just a few bands were studied with high-resolution.…”

High resolution analysis of C2D4 in the region of 600–1150 cm−1

“…As to the three Coriolis-type resonance interactions, the corresponding non-diagonal blocks of the Hamiltonian (1) can be written in the following form (see, e.g., Refs. [57][58][59] …”

On the determination of the intramolecular potential energy surface of polyatomic molecules: Hydrogen sulfide and formaldehyde as an illustration

“…From Refs. [53][54][55][56][57][58][59][60][61][62][63][64][65][66][67], we used 88 band centers of the three isotopic species as initial experimental data. Obtained from the fit is a set of 16 parameters of the potential function from Eq.…”
