There is a fair consistency between the proposed model of the process of photosynthesis and the spectra. The spectra show a proportionate change in the process with a change in energy.
Q3
IVR excitation is intended to make a comparison with the ground state IVR for S0 S1 and S2. It enables molecules to be in an inactive state from where they can release energy to return to S0.
Q5
Quantum yield = number of molecules in the reaction/number of photons that the photoreactive substance absorbs.
The fraction is expressed as a percentage by multiplying by 100.
= 87.5%
Q6
Through studying the measurement of vibrational excited and ground-state energy. Molecules at S0, S1, and S2 have distinguishing characteristics. It can also be studied in an ESP spectroscopy. It involves electronically exciting and quenching a molecule.
Q7
Molecules absorb and transmit discrete amounts of energy. The amount of energy emitted is characteristic of every substance.
