ethanol (10ug/ml). The spectrum was obtained using an Aminco-Bowman SPF equipped with a type IP21 Photomultiplier Tube and a 150-watt Xenon Lamp. The sample was placed in a quartz cell, Cat.No.Al-64051, and excited at 250 ιημ. A recording of the blank (one microliter of ethanol) is shown below the spectrum of anthracene.
