TEMPERATURE JUMP STUDIES IN THE NANOSECOND RANGE.
Abstract
An apparatus was developed to measure very fast chemical reactions in the nanosecond range and used for the investigation of various chemical systems of biological interest. It was possible to produce temperature jumps within nanoseconds by absorbing some of the light from a Q-switched Ruby-Laser. Such temperature jumps were applied to two non-biological systems, but these systems may be chemically connected to biological systems: bromthymoleblue as pH-indicator, methyleneblue, as an electron-transfer indicator. Although methyleneblue was not originally intended to be used for purposes of detection, it behaved abnormally at high light power densities. Thus, we were obliged to lookfurther into this compound. When methyleneblue proved to absorb the power of the Ruby-Laser non-linearly, a copper complex was used later on only for the absorption of the Laser energy. (Author)
