title: Room temperature phosphorimetry studies of caffeine and theophylline.
abstract: Room temperature phosphorimetry (RTP) of a mixture of two methylxanthines is described. The similar spectral characteristics of caffeine and theophylline require use of a separation procedure prior to RTP analysis. A facile and efficient separation method is reported, and the efficiency of the separation, and the RTP characteristics of the methylxanthines are presented.
