WebSilver halides are distinguished by the significantly high quan-tum efficiency of photochemical decomposition into silver and halogen. Mechanism of the process was suggested by Gurney and Mott and consists of several stages. 1 Under light absorption by silver halide electron and hole appears in the conductive and valence bands, accordingly.
WebIn general, according to the literature, five different types of photochemical quantum yields can be discussed ( ref. 16 ): 1. Apparent Integral Quantum Yield (14) 2. True Integral Quantum Yield (15) 3. Apparent Differential Quantum Yield (16) 4. True Differential Quantum Yield (17) 5. Partial Quantum Yield (18) iras loan benefitWebremained trapped. The HI was diluted to 0.5% in 1 atm of argon, and the bulb was wrapped in black cloth to prevent photochemical decomposition of HI. The HIrAr mixture was injected into the source region of the mass spectrometer through a 10 Hz repetition rate pulsed nozzle.
