Mid-Infrared Versus Far-Infrared (THz) Relative Intensities of Room-temperature Bacillus Spores
Journal Article

· Chemical Physics Letters
We have simultaneously recorded the mid-IR and far-IR (sometimes called terahertz, THz) spectra of the sporulated form of five common Bacillus bacteria: Bacillus subtilis ATCC 49760, Bacillus subtilis ATCC 6051, B. thuringiensis subsp. kurstaki ATCC 35866, Bacillus globigii 01, and B. atrophaeus 49337. The 295 K spectra were recorded from {approx}8 to 6,000 cm{sup -1} of samples deposited onto windows transparent in both the mid- and far-infrared. The results indicate that any room-temperature THz absorption features due to the bacterial spores are at least 28 times weaker (based on p-p noise) than the corresponding mid-IR amide I band.
