Use origin software to plot the graph.
Procedure
i) Input the data on x-axis and y-axis
ii) Select all and then plot
iii) when you click plot various options will be displayed. Select scatter and you will get the plot.
iv) Choose the best fit. Three spot coinciding through origin. And draw line as shown and find the slope.
v) Obtained slope is the answer.
All the steps are shown below.

Please help me answer the following
questions:
(iv) Calculate the molar extinction
coefficient (molar absorptivity) of the maximum absorbance of the
spectrum in Figure 1.
(v) Estimate the wavenumber gap
between the vibrational levels that gives the vibronic structure
apparent in the spectrum of anthracene. Check your answer before
proceeding to answer the next question. (Note: the peaks
are a single vibronic progression so you can average your estimates
of the wavenumber gap.)
