 The primary input data for the harmonic vibrational calculation is the Hessian matrix,
 which consists of second derivatives of the energy with respect to atomic positions.

 The Hessian matrix (in units of E<sub>h</sub>/a<sub>0</sub><sup>2</sup>) can be downloaded [here](./input/h2o_hessian.txt) for the H<sub>2</sub>O test case. 
 The first integer in the file is the number of atoms (which you should compare to the corresponding value from the geometry file as a test of consistency),

 ## Step 3: Mass-Weight the Hessian Matrix
 
 Divide each element of the Hessian matrix by the product of square-roots of the masses of the atoms associated with the given coordinates:
