Matrix-isolation infrared study of acetaldehyde: Host-dependent vibrational features
2022, Journal of Molecular SpectroscopyCitation Excerpt :CH3CHO has been subjected to intensive spectroscopic studies because of its simplicity and importance in various areas. Further, this molecule was subjected to vibrational spectroscopy by Weniger for the first time in the last century [2], and thenceforth, numerous gas-phase measurements have been reported [3-15], including high-resolution infrared studies [10-14]. A matrix-isolation study was carried out by Wiberg et al. in 1995 [9], and, to the best of our knowledge, no further measurements have been reported thus far.
High-resolution spectrum of the ν <inf>9</inf> band and reinvestigation of the ν <inf>8</inf> band of cis-CH <inf>3</inf>ONO
2012, Journal of Quantitative Spectroscopy and Radiative TransferCitation Excerpt :For acetaldehyde, we also developed another version of the BELGI code, which can deal with the torsional manifold arising from the ground state interacting with one isolated small-amplitude mode [14]. In the past we have also used a version of the BELGI code, which dealt with transitions belonging to one isolated infrared fundamental band [10–13]. The code used in the present study (BELGI-IR) is the updated version of this older code.
Infrared absorption cross-sections for acetaldehyde (CH<inf>3</inf>CHO) in the 3γm region
2011, Journal of Quantitative Spectroscopy and Radiative TransferCitation Excerpt :Since then, further efforts have been made to complete the initial work of Hollenstein and Günthard by using much higher spectral resolution. Kleiner [12–14] worked extensively with acetaldehyde by recording and assigning spectra of the fundamental torsion band (ν15) observed around 150 cm−1, the C–C–H bending fundamental (ν14) centered at 764 cm−1, and the ν5 and ν12 methyl C–H modes at 1430 cm−1 using a FTS equipped either with a long multipass cell or with a multinozzle long absorption path supersonic expansion. This was complemented by the investigation of Andrews [15], who assigned spectra of the ν9 C–C stretching fundamental at 867 cm−1 recorded using a diode laser with a slit-jet nozzle expansion and in a room-temperature gas cell using an FTS.
