2. a. Copper(II) acetate is a dimer, and the two copper atoms are strongly interacting. The epr spectrum consists of seven lines with intensity ratios 1:2:3:4:3:2:1. Copper nuclei have an I value of 2, and copper acetate consists of a ground state that is a singlet and an excited state that is a triplet. Explain the number and relative intensity of the lines in the spectrum. [For answer, see B. Bleaney and K. D. Bowers, Proc. Roy. Soc. (London), A214, 451 (1952).] b. What would you expect to happen to the signal intensity as a sample of copper acetate is cooled? Why?

W.P. Wijesundera et al. (Phys. Rev. A 51, 278 (1995)) attempted to determine the electron configuration of the ground state of lawrencium, element 103. The two contending configurations are [Rn]5f147s27p1 and [Rn]5f146d7s2. Write down the term symbols for each of these configurations, and identify the lowest level within each configuration. Which level would be lowest according to a simple estimate of spin–orbit coupling?
1. Using the values from the helium emission spectrum, generate a calibration curve on Microsoft Excel or other graphing software. If you are new to Microsoft Excel, specific instructions (with pictures) are given at the end of this lab and will be discussed in lab. a) In Excel, create a column labeled "scale position." This will serve as your x-values. Create another column labeled "wavelength." This will serve as your y-values. b) Enter the values for your scale position and wavelengths into each column. Do not put unit labels with the numbers. c) Create four separate graphs, one each for the four required types of trendlines ("linear", "logarithmic", "exponential", and "polynomial"). Each graph will have the same data plotted but have a different trendline. See the "Curve Fitting Using an Excel Spreadsheet" section at the end of this write-up for additional information about how to make these graphs. i. ALL graphs must conform to the requirements discussed in lab. 1) graph must take…
