In principle, the optical energy absorbed by a complex molecule raises that molecule to one of its excited states, and afterwards this excitation energy decays through the relaxation channels. Initially, electronically excited naphthalene emits photons and these emitted photons are absorbed by the acceptor molecule biacetyl, then excited biacetyl fluoresces. In this investigation radiative energy transfer-time is measured in cyclohexane by one and two-photon excitations. The UV-vis spectrum of biacetyl vapor at room temperature conditions was broad and structureless.
原则上,复杂分子吸收的光能会将该分子提升到其激发态之一,随后这种激发能通过弛豫通道衰减。最初,电子激发态的萘发射光子,这些发射出的光子被受体分子双乙酰吸收,然后被激发的双乙酰发出荧光。在本研究中,通过单光子和双光子激发在环己烷中测量辐射能量转移时间。室温条件下双乙酰蒸气的紫外可见光谱是宽谱且无结构的。
