Biological Evolution Flashcards
1
Q
H-bonds as shock adsorbers
A
dissipate electronic excitation energy into vibrational excitation energy
2
Q
why DNA?
A
not a lot of light with wavelength < 300 nm on Earth, DNA only absorbs well for wavelengths < 300 nm and have specific molecular mechanisms of radiationless deactivation that compete against potentially photoactive channels
3
Q
conical intersection
A
crossing of states
4
Q
photostable
A
low prob of staying in excited state, efficient quenching/IC
5
Q
photoreactive
A
low prob of returning to ground state
