Fill the blanks

a) The lowering of UV absorption intensity as polynucleotides form a double helix is called hyperchromic effect.

b) Intersystem crossing is slower than vibrational relaxation.

c) A vibrational transition is IR-active if the corresponding vibration scatters photons strongly.

d) The ratio of the number of quanta emitted to the number absorbed is called fluorescence.
