The data set available here provides spectra for a solution of benzene in methanol recorded from 230-290 nm using a Perkin-Elmer Lambda 4B spectrophotometer at different combinations of slit width, scan rate, and response time. The original spectra were collected in the late 1980s and print copies archived. To create this data set, the spectra were digitized using the WebPlotDigitizer app available here.
The data set is available as an Excel file with separate tabs for spectra (wavelength, absorbance) showing the affect on the spectrum of a change in slit width, scan rate, and response time. Representative plots of the data are shown below.
File: BenzeneSpectra
Tab 1: SlitWidth
slit widths: 0.25, 1.0, 2.0, and 4.0 nm
scan rate: 20 nm/min
response: 1
Tab 2: ScanRate
slit width: 1.0 nm
scan rates: 5, 10, 20, 60, 120, 200, 300, 750, and 1500 nm/min
response: 3
Tab 3: Response
slit width: 1.0 nm
scan rate: 60 nm/min
response: 1, 2, 3, 4, 5, 6, 7
The response settings likely are as follows (from Lambda 2 spectrophotometer):
1 = 0.1 s; 2 = 0.2 s; 3 = 0.5 s; 4 = 1.0 s; 5 = 2.0 s; 6 = 5.0 s; 7 = 10.0 s
