Which of the following transitions are allowed by selection rules?  Plesase in each case explain the answer by step. (1) 1S0 → 3P0 (2)  3D3 → 4D1/2 (3) 3S3 →  3P1 (4) 3G3 → 3G4 (5) 2F5/2 → 2P1/2

Propanone (acetone, (CH3)2CO) has a strong absorption at 189 nm and a weaker absorption at 280 nm. Identify the chromophore and assign the absorptions to π* ← n or π* ← π transitions.

Determine the number of vibrational modes that will be observed in (a) an Infrared experiment and (b) a Raman experiment for hydrazine (H₂N-NH2) in each of the following conformations - each one has a different point group: HH N-N HH (a) N-N HH HH (b) HH (c)

Identify the significant absorption peaks by labeling them right on the spectrumand includethe spectrum in your laboratory report. Absorption peaks corresponding to the followinggroups should be identified: C—H (SP3) C—H (SP2) C—H (aldehyde) O—H C=O C=C (aromatic)aromatic substitution pattern C—OC—X (if applicable)
