چکیده انگلیسی
The ν1(A1), Si-H stretching, ν2(A1) and ν4(E), Si-D stretchings, fundamental bands of HSiD3 have been recorded at an effective resolution of ca. 0.003 cmâ1 between 2080 and 2280 cmâ1 and between 1480 and 1720 cmâ1, respectively. Ro-vibrational transitions of the H28SiD3 isotopologue have been assigned in the two spectral ranges, about 700 belonging to ν1, with Jâ² up to 25 and K up to 21, and about 1600 to the ν2/ν4 dyad, with Jâ² up to 24 and Kâ² up to 19. The spectra of all the bands evidence the existence of several perturbations. The transitions of ν1 have been analyzed either neglecting or including in the model A1/E Coriolis-type interactions with nearby dark states. The Ï
2Â =Â 1 and Ï
4Â =Â 1 states have been fitted simultaneously taking into account several ro-vibrational interactions between them and, in addition, with the Ï
5 = 2, l = 0 component, and with few other close dark states. The standard deviation of the fit for both ν1 and the ν2/ν4 dyad is, however, more than one order of magnitude larger than the estimated experimental precision and is independent on the adopted model.
