Using the given values, absorbance and transmittance should be calculated. To derive the spectrum of the compound the graph between wavelength and absorbance should be constructed.
Diode array spectrophotometer is used for instrumental analysis. As it is composed with a single detector, the instrument is capable of monitoring one wavelength at a time. Diode array spectrophotometer is very fast in data acquisition, which allows building up multiple spectra for a single sample. The final spectrum is presented as an average of individual samples.
