  氩-乙炔范德华配合物的振动-旋转光谱

  摘要：

  摘要 对含有ArHCCH范德华配合物的分子束进行了红外激光吸收光谱研究。观察到两个独立的振动带，与 ν 3 和 ν 2 + ν 4 + ν 5 的单体费米二元组相关。结合已知的微波频率对红外数据进行分析，以获得振动起源、旋转常数和离心畸变常数。相对于基态，激发振动态的特征在于具有基本相同的键长，但有效键角却大不相同。用固定间隔内旋转模型分析大振幅弯曲运动，以提供一些角势信息。

  Abstract Infrared laser absorption spectroscopy has been carried out on a molecular beam containing the ArHCCH van der Waals complex. Two separate vibrational bands, associated with the monomer Fermi dyad of ν 3 and ν 2 + ν 4 + ν 5 , were observed. The IR data were analyzed in combination with known microwave frequencies to obtain vibrational origins, rotational constants, and centrifugal distortion

  Radio frequency spectroscopy and Stark effect measurements have been carried out on Ar⋅HCCH and Ar⋅DCCD produced in acetylene seeded argon beams. Because of the very small electric dipole moment, μ=0.02697(3) D, only the 110–111 transition and low frequency pure Stark transitions were observed. Observations are only compartible with a T-shaped equilibrium structure with an Ar to acetylene distance of 3.25(1)Å. Deuterium hyperfine data provide a 204.4(10) KHz value for eqQ of acetylene and arcos (√<cos2ϑ≳)=72(1)° for the complex.

  The total differential scattering cross sections for H2, N2, and Ar with C2H2 were measured on an in-plane crossed molecular beam apparatus at collision energies of 1051, 1056, and 929 K, respectively. Well resolved rainbow oscillations for N2 and Ar, and diffraction oscillations for H2, showed two interference effects. Effective spherical and anisotropic potentials were obtained from analysis using single channel and infinite-order-sudden (IOS) methods, based on the semiclassical Jeffreys–Wentzel–Kramers–Brillouin (JWKB) approximation. The damping of oscillations showed the importance of anisotropy in the pair potentials. Total differential scattering cross sections calculated using the IOS method were in excellent agreement with the experimental data.
