Figure 14
The first-order reaction rates observed for the 2ce3mpy, 2ce3epy, 2cp3mpy, Mix-I and Mix-II crystals. The increase in intensity of the IR peaks that are due to the CN stretching frequencies of the cyano groups is considered to give an estimate of the reaction rates. The values of C0 and Ct indicate the concentration of the 1-cyanoethyl and/or 1-cyanopropyl complex(es) at the irradiation times 0 and t, respectively. |
