  Bonding States of He, Ne and Ar in Solid C₆₀

  摘要：

  He, Ne and Ar are intercalated in a lattice of C60 under the conditions of ambient temperature and pressure. The mass-analyzed thermal desorption reveals that rare gases are desorbed above 400 K and their desorption amounts are not in impurity level but in stoichiometric level. X-Ray photoelectron spectra in the C1s and valence band regions show different peak profiles. These results indicate that He, Ne and Ar atoms in a C60 lattice are in the bonding state.

  The rotational and vibrational dynamics of argon–methane. II. Experiment and comparison with theory

  摘要：

  Presented here is a detailed comparison between the experimental near infrared spectrum of argon–methane and the results of a theoretical calculation based upon the methods described in a companion paper, hereafter referred to as paper I [T. G. A. Heijmen et al., J. Chem. Phys. 110, 5639 (1999), preceding paper]. Many of the bands in the spectrum are easily assigned directly from this comparison. The spectrum is shown to be highly sensitive to the anisotropy of the argon–methane potential surface and the agreement with the ab initio spectrum, although not quantitative, is very good. The predissociation linewidths observed in the experimental spectra are found to be strongly dependent upon the symmetry of the excited state. Symmetry considerations place restrictions on the final rotational states that can be accessed, possibly explaining the differences in the lifetimes.

  Integral cross sections for the bond-forming reaction CO2++Ar→ArC2++O have been measured as a function of collision energy in a guided-ion beam mass spectrometer. The energy dependence is consistent with an endoergic reaction. Since the title reaction is in competition with several charge-transfer processes, the cross section at the maximum is only 0.023 A2 at a collision energy of about 3 eV. Simple

  成键反应 CO2++Ar→ArC2++O 的积分截面已在引导离子束质谱仪中测量为碰撞能量的函数。能量依赖性与吸能反应一致。由于标题反应与几个电荷转移过程竞争，因此在约 3 eV 的碰撞能量下，最大横截面仅为 0.023 A2。简单的运动学考虑表明，在较高能量下横截面的衰减可能是由于 ArC2+ 的振动预离解。状态相关图用于讨论反应机理。
