The semiempirical PCILO method has been used to study stereochemistry of the intramolecular hydrogen bond O-H...0 in 2-methoxyphenol (guaiacol) and 2-methoxy-6-fonmyl phenol (o-vanillin). According to my calculations, the hydrogen bond in guaiacol is weak and has energy of 2.7 kJ/mole and forms a pl
