Plucinski Title: Optical absorption measurements and quantum-chemical simulations of optical properties of novel fluoro derivatives of pyrazoloquinoline Journal/Source: Chem. Phys., 370, 194-200, (2010); doi:10.1016/j.chemphys.2010.01.001 Data: table, diagram Energy/Wavelength range: ~ 190 - 450 nm Resolution: 1 nm Temperature: Temperature dependence: Pressure/Concentration: Phase: solution (acetonitrile, dichloromethane) pH: Comments: The UV-Vis absorption and fluorescence spectra were recorded in acetonitrile and dichloromethane (HPLC grade) solutions (concentrations approximately 0.001% w/w). Spectral positions of absorption maxima (in acetonitrile) are 220, 260, 316, 328 and 396 nm. Spectral positions of absorption maxima (in dichloromethane) are 262, 316, 330 and 398 nm.
