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.

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...
