What is another name for fluorometry?

• A. Molecular emission spectrophotometry
• B. Molecular absorption spectrophotometry
• C. Chromatographic fluorescence
• D. Photoemission spectroscopy

Answer: (A)

Fluorometry is all about exciting molecules and detecting the light they emit, so it falls under emission-based measurements rather than absorption. Describing it as molecular emission spectrophotometry captures this idea precisely: you’re measuring the emitted photons from the molecules after excitation. The other terms don’t fit as well because absorption spectrophotometry deals with what the sample absorbs (not emits), chromatographic fluorescence refers to a specific application in chromatography, and photoemission spectroscopy covers broader photoemission phenomena not limited to standard fluorometric detection.
