Abstract

By measuring the absorption of dilute aqueous solutions of <i>KI</i> with various known amounts of pure iodine added, the present writers have observed that the absorption coefficient at a wavelength of about 350 mµ is nearly proportional to the amount of iodine in the solution. Making use of this fact, the amount of excess iodine in additively <i>V</i>-colored <i>KI</i> crystal has been obtained. Taking into account that two iodine atoms are associated with a <i>V</i><sub>2</sub> center, the oscillator strength of the absorption band at 365 mµ has been estimated to be 1.10±0.16 by the Smakula formula.
