The T←S0 Absorption of the Acetophenone Crystal

Abstract
The polarization and Zeeman splitting of the T←S0 absorption were measured with the acetophenone single crystal at 4.2 K. From the analyses of the polarization behavior and the Zeeman splitting pattern, it is concluded that the 26110 cm−1 band is in-plane polarized and has the character of the n,π* type transition.
