Abstract
The radical cations of butatriene (BT+•) and tetramethylbutatriene (TMBT+•) have been stabilized in low-temperature halocarbon matrices and studied by ESR spectroscopy. The spectra of BT+• and TMBT+• exhibit isotropic hyperfine splittings of 8.3 G (4H) and 13.0 G (12H), respectively. The skew angles of BT+• (25°) and TMBT+• (50°) are estimated by comparing the experimental hyperfine splittings with those obtained by semiempirical MO calculations.
