On the study of high-resolution rovibrational spectrum of H2S in the region of 7300–7900cm−1

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

“…In a recent contribution [1], we presented results of analysis of the high-resolution Fourier transform spectrum of the H 2 S molecule in the region of the v ¼ v 1 þ 1 2 v 2 þ v 3 ¼ 3 polyad (7300-7900 cm À1 ). The goal of the present investigation is the high-resolution analysis of the H 2 S spectrum in the shorter wave region, namely, 8500-8900 cm À1 , where the next, v = 3.5 polyad is located.…”

“…Because the review of the earlier investigations of the H 2 S spectra was made in [1], we will not repeat it here. As to the high-resolution spectrum in the region discussed in the present study, it was mentioned in [2] and only a few information was reported: the numbers of assigned transitions (74 and 86), maximum values of the upper quantum numbers J and K a (J = 9, K a = 7 and J = 9, K a = 8), and values of the band centers (8697.142 and 8697.155 cm À1 ) for the parallel and perpendicular type bands, 3m 1 + m 2 and 2m 1 + m 2 + m 3 , respectively.…”

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 Fourier transform spectrum of H2S in the region of the second hexade

“…In the recent contributions [1,2], we presented results of analysis of the high-resolution Fourier transform spectrum of the H 2 S molecule in the regions of the v ¼ v 1 þ 1 2 v 2 þ v 3 ¼ 3 and v = 3.5 polyads (7300-7900 and 8500-8900 cm À1 , respectively). In the present work, we will present the results of the high-resolution analysis of the H 2 S spectrum in the longer wavelength region, namely, 5700-6650 cm À1 , where the v = 2.5 polyad is located.…”
