A Temperature Jump Apparatus with a Pressurized Cell

A pressurized cell system of Joule-heating type apparatus was found to be effective in eliminating the noise originated from shock waves, and to be convenient for handling the sample solution by eliminating the bubble problem. Methods of efficient data aquisition for a relaxation curve were described. The fluctuational aspect of the T-jump theory was extended and the relaxation times were shown to be proportional to the correlation of fluctuations over exchange rate.
