Please answer each part, with an explanation if possible. Thank you a ton.

Match the type of molecular spectroscopy described with its name. ( 3pts ) I. IR II. NMR III. Mass Spec a) Utilizes radio frequency electromagnetic radiation to detect the unique chemical environments of the nuclei in a given sample which helps construct or confirm a predicted molecular structure. b) Vibrational modes of specific bond types absorb unique energies which helps determine what functional groups are present in a given sample. c) An electron beam of 70eV bombards a sample to break it into positively charged fragments which can be analyzed to determine molecular structure and weight. 17
