|Issue Date:||Jul-1998||Citation:||Goh, K.L.,Ong, P.P.,Tan, T.L.,Wang, W.F.,Teo, H.H. (1998-07). The High-Resolution Infrared Spectrum of the v5 Band of Deuterated Formic Acid (DCOOH).

ScholarBank@NUS Repository.||Abstract:||The Fourier transform infrared spectrum of the v5 band of deuterated formic acid (DCOOH) has been measured with a resolution of 0.004 cm-1 in the frequency range of 1090-1180 cm-1. Using a Watson's A-reduced Hamiltonian in the Ir representation, a total of 1731 assigned unperturbed transitions have been analyzed to provide rovibrational constants for the upper state (v5 = 1) with a standard deviation of 0.000363 cm-1. The band is A type with an unperturbed band center at 1142.31075 ± 0.00002 cm-1. The band is expected to be perturbed by a nearby v4 band through a Fermi resonance term and possibly a Coriolis term. The resonance is particularly noticeable for Ka = 10, and 11, at high J values. About 215 perturbed lines were identified but they were not included in the final fit. © 1998 Academic Press.||Source Title:||Journal of Molecular Spectroscopy||URI:||http://scholarbank.nus.edu.sg/handle/10635/98279||ISSN:||00222852|
