摘要：
The gas-phase absorption spectrum of the nu-3 band of cyclopropenylidene (cyclic C3 H2) has been observed with a high-resolution Fourier transform infrared spectrometer. The ring molecule was generated by a microwave discharge in an allene and Ar mixture. The spectrum observed between 1250 and 1305 cm-1 was analyzed by using Watson's A-reduced Hamiltonian to determine the band origin (nu-0 = 1277.3711 +/- 0.0001 cm-1), rotational constants, and centrifugal distortion constants in the nu-3 state.
