摘要：

The infrared absorption spectrum of the nu6 and nu8 bands of disilane (Si2H6) was recorded at medium resolution (0.1-0.05 cm-1). A rotational analysis of the P(J) and R(J) structure of nu6 was carried out, yielding the band origin and information on the B constant of the ground and v6 = 1 states of the molecule, and on the D(J) centrifugal distortion constant. About 400 transitions of the nu8 band were assigned and analysed, giving information on the band origin and the rotational constants of the v8 = 1 state. Using the new and previous information on the vibrational SpeCtruM of Si2H6 and Si2D6, a force constant refinement was performed. Several force field models were tried and a discussion of the results is presented.
