✦ Synopsis

The present paper deals with the analysis of the microwave, millimeter-wave, and infrared spectra of 28 SiHF 3 in its ground, v 6 ϭ 1 and v 4 ϭ 1 excited states. The former was observed up to 1055 GHz leading to the determination of one octic centrifugal distortion constant, L J ϭ Ϫ0.0749(55) Hz. Furthermore the ͗k͉H͉k Ϯ 6͘ interaction term ͉h 3,GS ͉ ϭ 1.1032(70) mHz has been fitted from splittings of six K ϭ 3 lines. The excited states have been regarded as isolated ones. This enabled fits according the Q-, D-, and QD-reduction schemes proposed by E. I.
