Pure rotational Raman spectra of gaseous C6H6 and C6D6 yield the following rotational constants: B (C6H6) = 0.18960 cm-1 and B (C6D6) = 0.15681 cm-1. The moments of inertia of the molecules about any axis perpendicular to the C6 symmetry axis were calculated as I (C6H6) = 1.4759 x 10-45 kg/m2 and I (C6D6) = 1.7845 x 10-45 kg/m2. Calculate the C-C, C-H and C-D bond lengths.

1.Answer the following questions A) Describe how the molecules in a gas produce an emission spectrum. How is this useful in astronomy if we assume that the laws of physics are the same everywhere? B) Why was the uniform expansion model adopted? How does this lead to a necessary differentiation between classical and cosmological redshift

Look at situation where there are 2 molecules of the same protein, which means same primary sequence. In addition they fold at the same time in the same funnel. Each protein, which is represented by a marble, is predicted to take a special path as it moves down the funnel during the folding process. While it folds, it is possible that the two proteins collide on the way down the funnel, and as a result of this collision, one or...

3. Pure expectations theory: Two-year bonds Which of the following is consistent with the pure expectations theory of the yield curve? Check all that apply. A flat yield curve suggests that the market thinks interest rates in the future will be the same as they are today. A downward-sloping yield curve suggests that the market thinks interest rates in the future will be lower than they are today. A flat yield curve suggests that the market thinks interest rates in...
