Abstract

Here we present an original study of the effect of hydration on THz absorption signatures in biomolecules (lactose monohydrate and biotin) and bioparticles (Bacillus thuringiensis and Bacillus cereus spores). We observe a “red-shift” in center frequency with increasing hydration in all samples, consistent with Lorentzian-oscillator behavior. But the effect of hydration on linewidth is ambiguous, sometimes increasing the linewidth (consistent with Lorentzian behavior) and sometimes decreasing the linewidth.
