Which analytical technique uses the measurement of the mass-to-charge ratio of charged particles to identify and quantify molecules in a sample?

💡 Solution & Explanation

Mass spectrometry is an analytical technique that measures the mass-to-charge ratio of ionized chemical species to determine molecular weight and elucidate structural formulas. Ultraviolet-visible and infrared spectroscopy rely on the absorption of electromagnetic radiation at specific wavelengths to identify functional groups and electronic transitions. Nuclear magnetic resonance spectroscopy probes the magnetic properties of atomic nuclei to analyze molecular geometry and connectivity.
