“…For the system optically pumped by the 9 P͑34͒ CO 2 laser line, assignment of the R͑132,10͒ CO transition as the IR pump absorption 15 was supported by combination loops and corrected an earlier proposal. 32 For the 9 P͑10͒ system, the R͑113 Ϫ ,30͒ CO A Ϫ pump assignment [10][11] was confirmed by IR-radio-frequency double resonance. 13 The R͑1310,20͒ CO transition was assigned [10][11] as the pump in the 9 P͑22͒ system; although we have not been able to detect the weak ͑1310͒ CO A subband in our spectrum to provide independent support for this identification, the earlier analysis and transition wave numbers appear well founded.…”

Articles you may be interested inGround and asymmetric CO-stretch excited state tunneling splittings in the formic acid dimer Torsionally excited nϭ1 and nϭ2 subbands of the CO-stretching fundamental have been assigned in the Fourier transform infrared spectrum of 13 CH 3 OH recorded at a resolution of 0.002 cm Ϫ1 . For the nϭ1 torsional state, subbands with K values up to 7 have been identified for A torsional symmetry and up to 5 for E symmetry. For nϭ2, four subbands have so far been assigned. Subband origins have been obtained by fitting the observed wave numbers to J(Jϩ1) power-series expansions. The expansion parameters represent the data compactly to close to the experimental uncertainty in the absence of line blending or perturbations. Significant downshifting of the nϭ1 origins is observed, correlated closely with proximity to the nϭ0 OH-bending state. J-localized perturbations have been observed and characterized for several subbands. Two of the far-infrared laser lines optically pumped by the 10R͑14͒ CO 2 laser line have been assigned.
