Resumen
The coherent Raman emission from primary alcohols [CH3(CH2)nOH, n = 0–10], 2-propyl alcohol and
tert-butyl alcohol was studied using a frequency-doubled Nd :YAG pump laser (532 nm). We show that
increases in the chain length (CH2 groups) and the number of CH3 groups in the alcohols (CH3 >
CH2) enhance the Raman emission efficiency. Theoretical density functional theory (DFT) calculations
and frequency scaling allow one to associate the vibrational wavenumbers with the molecular fragment
responsible for the vibration. We obtained good agreement between the observed phenomena and the
predictions of the theory FONACIT(Grant G97000593).
