摘要：

The (1+1) resonance enhanced two-photon ionization spectra of NO-methane van der Waals (vdW) complexes associated with the A(2) Sigma(+)-X(2)II transition of the NO moiety were measured using a time-of-flight mass spectrometer. The band origin of NO-CH4 vdW complex is determined as 44103.7 cm(-1). In the low transition energy region of 44080-44180 cm(-1), the origin band and two vdW bands were observed and each of the bands consisted of four peaks due to the internal rotation of methane. An analysis of the internal rotation gave the V-3 anisotropic parameters of 114-153 and 35 cm(-1) in the A(2) Sigma(+) and X(2)II states, respectively.
