A. Faye et al., High-resolution Fourier transform spectroscopy of N-14(2): Analysis of the(1-0), (2-1) bands of the B-3 Pi(g)-W-3 Delta(u) system, J MOL SPECT, 197(2), 1999, pp. 147-157
The extension of high-resolution observation of the electronic emission spe
ctrum of N-14(2) toward the infrared domain is presented. To date, rotation
al analysis of the widely investigated spectrum of the Nz molecule was done
in a spectral domain ranging from 2500 cm(-1) to the UV. We have recorded
for the first time the infrared part of the N-14(2) spectrum from 1250 to 2
250 cm(-1), using the Fourier transform spectrometer of Laboratoire de Phot
ophysique Moleculaire (LPPM) at an unapodized resolution of 0.0043 cm(-1).
A complete rotational analysis is performed for the (1 --> 0), (2 --> 1), (
0 <-- 1), (1 <-- 2) bands of the B(3)Pi(g)-W(3)Delta(u) system, not include
d in any previous analysis. Spectroscopic parameters for the v = 0, v = 1,
v = 2 levels of the B(3)Pi(g) and the W(3)Delta(u) states, consistent with
those previously reported but with improved accuracy, an obtained from the
experimental wavenumbers by a nonlinear least-squares procedure. (C) 1999 A
