The microwave spectrum of excited vibrational states of silyl bromide

Abstract The microwave spectra of the J = 3 ← 2 and 4 ← 3 transitions were measured for all vibrationally excited states below 1000 cm −1 , and the rotational and nuclear quadrupole coupling parameters were determined for these states. In addition, a strong Coriolis resonance between the v 2 = 1 and v 5 = 1 states was observed and analyzed.
