Data: diagram, table

Energy/Wavelength range: ~ 50000 - 80000 cm-1 (~ 125 - 200 nm)

Resolution: 

Temperature: 24 K; 298 K

Temperature dependence: 

Pressure/Concentration:

Comments: In the condensed-phase spectra, absorption in the regions below 50000 cm-1 was determined using room-temperature acetonitrile 
solutions, while the spectra beyond 50000 cm-1 are of neat films at 24 K.
