Abstract :
Terahertz transmission spectra of frozen gelatin solution were measured. The observed spectrum shows that the scattering of ice crystal is negligibly small. The absorbance of liquid water in the sample was confirmed by subtracting those of ice and freeze dried gelatin from the observed spectra.
