3 - 17 (4) When automatic saving is set, data will be saved after completion of measurement. Upon opening its file, a data processing window will appear as in Fig. 3-12. Although a peak table can be displayed, simultaneous display of rate calculation (kinetics) result and peak table cannot be selected. Fig. 3-12 shows a spectrum and the result of rate calculation. This is selectable from the View menu. Unless automatic saving is set, select the Save As command from the File menu...

3 - 20 3.6 Calculating the Phosphorescence Life This is the function for calculating phosphorescence life from the measurement result (phosphorescence attenuation curve). Replacing data value at T1 with I 0, I0/e time (T2) is found, and T1, T2 and τ (phosphorescence life) = T2 - T1 are displayed. Select the phosphorescence life command from the data (D) menu or click the button on the Processing toolbar. A window as in Fig. 3-15 will appear. Fig. 3-15 Move...
