Abstract

MANY attempts have been made to explain the discrepancy between the scotopic luminosity curve and the absorption spectrum of visual purple. Recently, Dartnall and Goodeve1 have applied the Stark-Einstein law in order to express the luminosity curve in terms of quanta and have shown that the resulting correction was insufficient.
