Magnetic circular dichroism (MCD) of the rydberg transitions in benzene using synchrotron radiation

The magnetic circular dichroism of benzene vapor has been studied using synchrotron radiation with attention focused on the 3R', 3R', and 3R''' region. The data are consistent with assignments, 1 A tg → 1 A 2u , 1 E 1u for R, R', respectively, from π(e ig ) → n p excitations and support assignment of R', R''' to 1 A 1g → 1 E 1u transitions from π(e 1g ) → n f excitations.
