Temperature Jump (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Temperature jump is a technique used in the study of chemical kinetics. It usually involves the discharging of a capacitor (in the kV range) through a small volume (>ml) of a conducting solution containing the molecule/reaction to be studied. In some versions of the apparatus used, the solution is heated instead by the output of a pulsed laser which emits in the near infra-red. When laser heating is employed, the solution need not be conducting. In both cases, the temperature of the solution is caused to rise by a small amount in microseconds (or less in the case of laser heating). This allows the study of the shift in equilibrium of reactions that equilibrate in milliseconds (or microseconds with laser temperature jump), these changes most commonly being observed using absorption spectroscopy or fluorescence spectroscopy.
