摘要：

The rotationally resolved, Stark split spectrum of the v(1) + 3v(3) band of acetylene has been investigated with a high resolution molecular beam laser spectrometer. The results indicate a field induced coupling of the \1030(0)0(0)]) upper state with the \0040(0)0(0)]) state. The number of observed transitions was sufficient to allow a detailed analysis of the field induced coupling. The J-dependent polarisability and anisotropy of the polarisability of the \1030(0)0(0)]) state were measured as well as the anisotropy of the polarisability of the ground state (1.071 Angstrom(3)). The coupling strength to the \0040(0)0(0)]) state, and the origin of the 4v(3) band were determined to be 0.0696 D and 12671.50 cm(-1). The latter has been compared with predictions made by local mode theory.
