✦ Synopsis

The rot ati on-vibration spectr um of hydraz ine vapour has bee n measu red fro m 250 t o 750 em-I. Th e t orsional vibration bands arising fr om the t ransition of n: 0 --+ 1, 0 --+ 2 and I --+ 2 were assigned . Th e centres of the bands were loca ted at 3 76 ,74, 665•9 and 289 '5 cm-1 , respect ively . By the an alysis of the fine structure, rotational constants were determined . F rom t hese the bond lengths and t he bond ang les of the molecule were ca lculat ed . According to t he ir regul ar spacing of the Q-branch near the cent re of the band, t he asymmet ry factor E was est imated to be very small, and the molecule appears to have a righ t-angle struct ure.
