Assignment

1. Draw the structure of Abscisic acid. Optimize the geometry of the molecule. Perform a confromational analysis by calcualting the dihedral angle of the molecule at different orientaions. 

2. Draw the structure of Tamoxifen. Optimize the geometry of the molecule. Perform a conformational analysis by calculating the bond angle, bond length and dihedral angle of the molecule at different orientations by changing its length and angle.
