将溶剂从H2O改变为D2O显著影响交替G·C DNA双链体中初始激发电子态分支为两个不同的衰变通道。在D2O中使超过一半的所有激发态失活的较慢的多位点PCET通道在H2O中变得弱六倍。
Changing the solvent from H2O to D2O dramatically affects the branching of the initial excited electronic states in an alternating G·C DNA duplex into two distinct decay channels. The slower, multisite PCET channel that deactivates more than half of all excited states in D2O becomes six times weaker in H2O.
