摘要: Abstract The A 1A″ (nπ*) and B 1A′ (ππ*) states of isoquinoline are only 1106 cm−1 apart strongly coupled through out-of-plane vibrations. Computer simulation rotational contours confirms the 000(ππ*) assignment shows that there is appreciable Coriolis coupling in a01(nπ*) b01 bands, where νa νb involved vibronic to ππ* state.
