We present the mid-IR (400-1800 cm-1) spectra of 9-ethyl guanine, guanosine, and 2-deoxyguanosine measured by IR-UV double-resonance spectroscopy. We compare the recorded mid-IR spectra with the spectra of the most stable structures obtained from RI-MP2 and RI-DFT-D calculations. The results confirm the enol form for all structures and demonstrate the efficacy of a new approach to DFT calculations that includes dispersion interactions.
V práci jsou publikována experimentální a teoreticky spočtená spektra 9-ethyl guaninu, guanosinu a 2-deoxyguanosinu. V práci je demonstrována úspěšnost predikce spekter metodou RI-DFT-D.
