Infrared spectrum of methanol (CH3OH) exhibits a peak at 3300 cm and 3000 cm corresponding to the O-H and C-H stretching mode, respectively. If all the H atom in CH₂OH are replaced by a deuterium atom, determine the expected position of the O-D and C-D stretching modes (assume that bond strength k values are identical for both O-H and O-D; C-H and C-D). Mention one other characteristic stretching peak you would expect in the IR spectrum of methanol (CH3OH) other than these two peaks? What will be the effect of the replacement of H by D on this peak?

This problem deals with fluorescence and phosphorescence. (a) Someone says that when the quantum yield of molecule (donor) is reduced to 50% of its original value because of the presence of a quencher (acceptor) allowing fluorescent resonance energy transfer, then (i) the efficiency of FRET is 50%, and (ii) the distance between donor and acceptor is 50% of R0. Support these claims if they are true. Correct these claims if they are false. (b) Five mini questions. (i) Fluorescence combines which two of the following transitions: electronic, vibrational, rotational? (ii) Which is helped more by heavy atoms in the emitting molecule: fluorescence, phosphorescence?(iii) The Frank-Condon principle plays a role in which process: absorption, vibrational relaxation, intersystem crossing? (iv) What type of shift is observed for fluorescence: redshift, blueshift? (v) Selection rules indicate that which process is forbidden: fluorescence, phosphorescence, both, neither?
