“…The large number of level crossings with ⌬(k Ϫ l ) ϭ Ϯ3 and Ϯ6 interaction mechanisms give rise to numerous forbidden, but perturbation-allowed lines, their JЉ and KЉ being as large as 30. This enables determination with very high precision of the C 0 , D K 0 , and H K 0 values which now supercede the poorer and less complete values hitherto available (14). We have fitted the excited state energies with two different models corresponding to two different Hamiltonians.…”

“…We have used the same spectra as for the study of 5 (14). In brief, the resolution was 3.3 ϫ 10 Ϫ3 cm Ϫ1 (1/maximum optical path difference), the precision ca.…”

“…[7] The infrared spectrum of silane, SiH 4 , was first studied in 1935 by Steward and Nielsen [8] and a set of fundamental frequencies for the most abundant isotopomer was first obtained in 1942 by Nielsen and coworkers. [9] The isotopomers of SiH 4 have been the subject of considerable high-resolution experimental work; for instance, we note [10,11] [15,16] for 28 SiHD 3 , and [17,18] for 28 SiD 4 . The molecule is of considerable astrophysical interest, having been detected spectroscopically in the atmospheres of Jupiter and Saturn [19] and in the interstellar gas cloud surrounding the carbon star IRC+10 216 [20] Until most recently, only fairly low-resolution data [21] were available for SiH 2 D 2 ; as the present paper was being prepared for publication, a high-resolution study [22] of the {ν 3 , ν 4 , ν 5 , ν 7 , ν 9 } Coriolis resonance polyad appeared, in which assignments were facilitated by mixed basis set CCSD(T) and MP2 calculations of the quartic force field.…”
