摘要：
Twenty-four rotational lines associated with the nu-5 (sigma-u) antisymmetric stretch vibration of C-7 have been measured by high resolution diode laser absorption spectroscopy of a supersonic carbon cluster beam. A simultaneous fit of spectra connecting the ground state with upsilon = 1 of nu-4 (J.R. Heath et al., Science 249 (1990) 895, J.R. Heath and R.J. Saykally, J. Chem. Phys. 94 (1991) 1724) and nu-5 produces the following molecular constants for the nu-5 state (in cm-1): nu-5= 1898.3758(8), B' =0.030556(15), D'= -0.16(11) X 10(-7), H'= -0.44(31) x 10(-11).
