Figure 7
Temperature-dependent series of far-IR absorption spectra of polycrystalline natural-abundance adenine. The temperature range is in 10 K increments from 80 K to 300 K. The spectra for 110 K and 100 K were left out for clarity. The bands indicated by asterisks are poorly resolved in the 300 K spectra, but are clearly present in the 80 K spectra. The data are not corrected for changes in source intensity. |
