Abstract

The BH2 and CH− 2 radicals have been generated and trapped in rare gas matrices for ESR(electron spin resonance) investigation. Theoretical calculations were conducted on these radicals and the CH+ 2 cation for detailed comparison with the experimental results. The observed magnetic parameters (MHz) for 13 CH− 2 in neon matrices at 4 K were: g iso =2.0027(3); 13 C; --A iso--=59(1) and H; --A iso--=45(1). For 11 BH2 in argon at 4 K the results were: g iso =2.0016(3); 11 B; A iso=358(2) and H; --A iso--=38(1). The electronic structure information obtained for these small radicals from theoretical and experimental results is discussed and compared with other related molecules.
