Definition
Meaning and Definition
A scientific technique that measures the absorption of microwave radiation by molecules to study their structure and properties.
A branch of rotational spectroscopy that analyses the interaction of matter with electromagnetic radiation in the microwave frequency range (typically 300 MHz to 300 GHz), used to determine molecular geometries, dipole moments, and rotational constants.
Dialectal Variation

Common Mistakes When Using “microwave spectroscopy”
- Using 'microwave spectroscopy' to refer to cooking food in a microwave oven. Misspelling as 'micro-wave spectroscopy'. Using it as a verb (e.g., 'to microwave spectroscopy a sample' is incorrect).
FAQ
Frequently Asked Questions
No, they are completely different. Microwave ovens use microwave radiation to heat food by exciting water molecules. Microwave spectroscopy uses controlled, low-power microwaves to probe the rotational energy levels of molecules for analytical purposes.
It is most effective for polar molecules in the gas phase, as they must have a permanent electric dipole moment to interact with the microwave radiation. Small to medium-sized molecules are typical targets.
It provides extremely high precision and resolution for measuring rotational constants, which allows for the accurate determination of molecular structures, bond lengths, and angles.
It is generally used as an uncountable noun (e.g., 'using microwave spectroscopy'). You would not typically say 'a microwave spectroscopy' or 'microwave spectroscopies'.
A scientific technique that measures the absorption of microwave radiation by molecules to study their structure and properties.
Microwave spectroscopy is usually technical/scientific in register.
Microwave spectroscopy: in British English it is pronounced /ˈmaɪ.krə.weɪv spekˈtrɒs.kə.pi/, and in American English it is pronounced /ˈmaɪ.kroʊ.weɪv spɛkˈtrɑ.skə.pi/. Tap the audio buttons above to hear it.
