Abstract
The B3LYР/6-31( p , d ) density functional method is applied to pheromones of the forest xylophagous insects Ips typographus L. , Monochamus urussovi Fisch ., and Monochamus galloprovincialis Oliv . to calculate the absorption spectra and find excited states. The calculated results are used to assess the possible activity of the molecules when they are affected by solar radiation.
