Sažetak
The dielectric loss ε'' of dilute solutions of five newly synthesized phthalazine derivatives in benzene has been studied in the microwave region between 0.3 and 15 GHz at 20°C. The data have been analysed for two or three absorption regions. The results are interpreted in terms of dipole reorientation by molecular and intermolecular rotation. The activity of these compounds on some fungi was determined and a linear relation was found between this activity and the intramolecular orientation of those compounds.
