High-resolution FTIR spectrum of the ν12 band of ethylene-d (C2H3D)

The ν12 band of ethylene-1-13C (13C12CH4) by high-resolution FTIR spectroscopy

“…Likewise, we had studied the m 12 bands of 12 C 2 D 4 [14], of cis-12 C 2 H 2 D 2 [18], of trans-12 C 2 H 2 D 2 [19], of 13 C 2 H 4 [22] and of 12 C 2 H 3 D [25] at high-resolution to improve on or to derive new ground and m 12 = 1 rovibrational constants. The present work is aimed at the analysis of the m 12 band of 13 C 12 CH 4 which was measured with a resolution of 0.0063 cm À1 .…”

High-resolution FTIR measurement and analysis of the ν3 band of C2H3D

“…The same nonlinear least-squares program for fitting asymmetric rotor spectra employed in the analysis of the m 12 band of C 2 H 3 D [9] was used for fitting the assigned transitions of the m 3 band. The program uses a Watson's Hamiltonian [12] with an I r representation in A-reduction.…”

“…Infrared studies on C 2 H 3 D ranging from low and medium resolution [1][2][3][4][5] to high resolution [6][7][8][9] have been conducted in the past three decades. In addition, the pure rotational spectra of C 2 H 3 D were measured and analysed by microwave spectroscopy [10].…”

“…The 730-780 cm À1 and 830-890 cm À1 regions of C 2 H 3 D were investigated separately by Herbin et al [6,7] using a tunable diode laser spectrometer. The latest of the C 2 H 3 D studies was done in 2004 by Tan et al [9] using the Fourier transform infrared technique in the 1340-1460 cm À1 region. From their work, upper state (m 12 = 1) rovibrational constants of the m 12 band of C 2 H 3 D had been derived for the first time.…”

High-resolution infrared analysis of the ν7 band of cis-ethylene-d2 (cis-C2H2D2)

“…The band center of m 7 has been found to be 842.20957 ± 0.00004 cm À1 . This investigation adds to our interest in high-resolution FTIR studies of the ethene or ethylene (C 2 H 4 ) molecule and its isotopomers [10][11][12][13][14].…”
