In 1962 Max Perutz and John Kendrew recieved the Nobel Prize in Chemistry for solving the crystal structure of myglobin, a protein involved in oxygen transport in mammalian muscle tissue. In a few sentences, describe one technique that we have studied that can be used to solve a protein structure. Use equations and/or words to formulate your answer.

What is the typical rotational frequency frot for a molecule like n2 at room temperature (25∘c)? assume that d for this molecule is 1å=10−10m. take the total mass of an n2 molecule to be mn2=4.65×10−26kg. you will need to account for rotations around two axes (not just one) to find the correct frequency. express frot numerically in hertz, to three significant figures.
