The Raman spectrum of gaseous (C2H2)-C-13 was recorded with charge-cou
pled device camera detection. The vibration-rotation bands of the fund
amentals nu(1) (in Fermi resonance with nu(2) + 2 nu(5)), nu(2) and nu
(4), the overtones 2 nu(2), 2 nu(4) and 2 nu(5) and the combinations n
u(1) + nu(2), nu(1) + nu(4) and nu(3) + nu(5) are presented and discus
sed. Some Q-branches of (CCH2)-C-12-C-13 were also detected. (C) 1998
