"Physical Chemistry Chemical Physics" . "The electronic and vibrational spectra of the clusters of 2-aminopyridine (2AP) with one and two water molecules have been measured by using resonant two-photon ionization (R2PI) and IR-UV ion depletion spectroscopy (IR/R2PI). Under microhydration the aromatic nitrogen forms a very strong H-bond with water. The H-bonded OH stretching vibrations for 2AP.DOT.H2O and 2AP.DOT.(H2O)2 exhibit a red shift of 254 and 413 cm-1, respectively, relative to the symmetric stretching vibration of free water. In addition water forms a H-bond with the amino group, resulting in a cyclic structure for both clusters. Due to a reduced geometric strain, two water molecules exhibit stronger H-bonds. These results are well supported by calculations on the density functional theory level." . .
