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 different relaxation channels. Initially, electronically excited naphthalene emits photons in the phosphorescence band of naphthalene and these emitted photons are absorbed by the acceptor molecule biacetyl, then excited biacetyl phosphoresces. In this investigation, sensitized phosphorescence decay times in different conditions were measured for naphthalene-biacetyl system in the vapor phase. The ultraviolet-visible 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不同的弛豫通道衰减。最初，电子激发态的萘在萘的磷光带中发射光子，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生磷光。在本研究中，测量了气相中萘 - 双乙酰体系在不同条件下的敏化磷光衰减时间。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。
