Geometry of the Internal Dynamics of the ~(12)C~(13)CH_(3)~(+) Carbocation

摘要

The internal dynamics of the ~(12)C~(13)CH_(3)~(+) isotopomer of the simplest carbocation is considered to be a distorted dynamics of its symmetric C_(2)H_(3)~(+) isotopomer. By using the group-chain methods and assuming quite naturally that the carbocation equilibrium structures continue to be planar and the nonrigid motion occurring between them is retained upon this isotopic substitution, a simple algebraic model is constructed to describe the spectrum of the ~(12)C~(13)CH_(3)~(+) isotopomer. The correctness of the model is limited only by that of the adopted geometrical symmetry of internal dynamics of the C_(2)H_(3)~(+) isotopomer.
