By electrophysiological patch clamp recordings, we probe the response of neuronal model cells to photoexcitation by short light pulses, excluding other pathways than a photoelectrical coupling, to be of passive nature only. (european-mrs.com)
This ESR will study different photoactive (bio) molecules following photoexcitation. (x-probe.org)
Upon a photoexcitation, the S0 state rapidly converts into an excited state where Au - Au covalent bonds are formed among Au ions aligned in a linear geometry. (sciencedaily.com)
