Question

After an induced absorption process of an intensity, there are (without population inversion) transitions between:a) vibrational and rotational levels in the infrared region, we obtainb) vibrational levels exclusively in the infrared regionc) vibrational and rotational levels in the microwave regiond) transitions between nuclear spin levels in the radio frequency region

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.
