Beta-carboline (betaC) alkaloids are present in a wide range of biological systems and play a variety of significant photodependent roles. In this work, a study of the aqueous solution-phase photochemistry, photophysics, and spectroscopy of three important betaCs [norharmane (nHo), harmane (Ho), and harmine (Ha)] and two betaC derivatives [N-methylnorharmane (N-Me-nHo) and N-methylharmane (N-Me-Ho)] upon one- and two-photon excitation is presented. The results obtained depend significantly on pH, the ambient oxygen concentration, and the betaC substituent and provide unique insight into a variety of fundamental photophysical phenomena. The data reported herein should not only help to understand the roles played by betaC alkaloids in biological systems but should also help in the development of methods by which the photoinduced behavior of these important compounds can be controlled.
