  摘要：

  摘要迄今为止，除了氢化物 AsH 和 SbH 之外，几乎没有实验证据表明存在游离的亚胂酸和亚锑酸。在此，我们报告了在固体氩基质中分别从乙炔基胂和乙炔基锡宾光生成三重乙炔基胂烯（HCCAs）和三重乙炔基锡宾烯（HCCSb）的情况。利用红外光谱鉴定了这些产物，并借助理论预测解释了相关的紫外吸收光谱。

  The gas-phase acidities of methylidynephosphine, HC=P. ethylidynephosphine. CH3C=P. and ethylidynearsine, CH3C=As, have been measured by means of Fourier Transform Ion Cyclotron Resonance (FTICR) mass spectrometry and calculated Lit the CCSD(T)/6-311+G(3df,2p)//QCISD/ 6-311 + G(df.p) level of theory. An analysis of these results shows that, in contrast to the well-known fact that HC=N is a stronger acid than CH3C=N, CH3C=P and CH3C=As are more acidic than HC=P and HC=As, respectively. The most important consequence of this unexpected effect is that while HC=P and HC=As are found to be weaker acids than HC=N. the opposite trend is found for the corresponding methyl derivatives, the acidity of which increases as CH3C=N < CH3C=P < CH3C=As. Also the effects of deprotonation on the structures and the vibrational frequencies of HC=X and CH3C=X (X=N, P, As) compounds are qualitatively similar. but quantitatively very different for nitrogen- as compared with phosphorus- and arsenic-containing compounds. A rationalization of these differences in terms of the bonding differences is presented.
