Abstract
The ν1(A1) and ν4(E) Si-H stretching fundamentals of H3SiD have been recorded at an effective resolution of 0.006 cm-1 between 2050 and 2300 cm-1. A total of about 2500 rovibrational transitions of the H328SiD isotopomer have been assigned with J′ up to 27 and K′ up to 22. A large number of "perturbation allowed" Δk = ±3 transitions have been identified in both the ν1 and ν4 bands. The assigned transitions have been analyzed using two different theoretical models, which took into account several rovibrational interactions between and within the ν1 = 1 and ν4 = 1 states, yielding a standard deviation of each fit of ca. 0.0004 cm-1, which may be compared with the experimental precision (ca. 0.0001 cm-1). Improved ground state parameters have also been obtained by means of ground state combination differences. © 1997 Academic Press.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
