Spectroscopy - correct answer _____ is the study of the interaction between radiation
and matter.
Spectrometer - correct answer A _____ is an optical instrument used to measure
properties of light over a specific portion of the electromagnetic spectrum, typically used
in spectroscopic analysis to identify materials.
Mass spectrometry - correct answer __________ is an analytical technique used to
measure the mass-to-charge ratio of ions.
Infrared spectroscopy - correct answer __________ is a form of absorption
spectroscopy that develops information about the structure of molecular substances
from various covalent bond vibrational modes.
Nuclear magnetic resonance spectroscopy - correct answer __________ exploits the
magnetic properties of certain nuclei. The most important applications for the organic
