Abstract
Low frequency vibrational modes of furosemide were measured with terahertz time domain spectroscopy at room temperature. The different crystalline forms of furosemide were also measured. A clear difference between their spectra was observed. This makes the identification of polymorphs of furosemide easy and quick.
