摘要：

Argon resonance photoionization of CHFCI2, CDFC12, CH2Cl2, CD2C12, and CHC13, during condensation with excess argon at 15 K produced a new 1197-cm-1 infrared absorption which is assigned toCCl2+. Chlorine and carbon-13 isotopic data verify the molecular identity and provide a 133° valence angle calculation. The markedly increased mode for CC12+ at 1197 cm-1 above CC12 at 746 cm-1 is attributed to enhanced ir bonding in the cation. Observation of the CCIBr+ and CBr2+ cations at 1122 and 1019 cm-1, respectively, in studies with CH2ClBr and CHFBr2, CDFBr2, CH2Br2, and CD2Br2 reinforces the identification of CCI2+.
