A 600 MHz NMR has a signal to noise ratio of 1000 for a proton standard. The 400 MHz NMR has a signal to noise ratio of 200 for a proton standard. If it takes 20 minutes to get an acceptable signal to noise ratio for a sample on the 600 MHz NMR, how long will it take you to achieve the same signal to noise ratio on the 400 MHz NMR?
Suppose a student is preparing a set of standard solutions for use in a spectrophotometric study. If percent transmittance, %T, were measured in the standard solutions before the color had a chance to fully develop, the measured value would be compared with solutions that have allowed the color to fully develop.

The percent transmission, % T, is defined as follows. percent transmission = х 100% 1, = intensity of the light entering the sample | intensity of the light leaving the sample sample If the sample absorbs no light, I = lo, the percent transmittance will be equal to 100%. If the sample absorbs the light completely, I = 0, the percent transmittance will be equal to 0. Thus, the greater the amount of light absorbed by the sample, the smaller the percent transmittance. You are given the following solutions, E will have the lowest %T and A will have the lowest absorbance. The lambda max for these solution should be around 620 nm. А В D E

2. Plot 1/A (y-axis) vs 1/n2 (x-axis) for hydrogen and attach your graph to the back of this handout. Excel graphs are not permitted. Your graph should have: a title, proper axis scaling, axes labelled including units, data points shown clearly eg. dot in a circle, best straight line drawn, and the coordinates (x,y) of the points on the straight line chosen to calculate the slope. Never use data points to calculate the slope! Show slope calculation directly on the graph. 3. a) From your graph, calculate the experimental value of R, the Rydberg constant. (Note- this is the absolute value of your slope): b) Based on the theoretical value of R, 1.0974 x 107 m1, calculate your % error:
