6. (35 pats) A chain segment of three bonds (four atoms) has the following Cartesian coordinates, x,y, and z : 114.93443.15412.235216.27943.62912.431317.21542.66313.112416.91942.05514.135 (i) Calculate the rotation angle of the second bond. Calculate the bond angle between second and third bonds. How many rotational angles could you calculate from given coordinate information? (ii) Consider the atoms are connected with elastic springs, where the potential function for each bond has the following form Vi=k(lilo)2 where k is the force constant (322kcal/mol),li is the bond length and lo is the equilibrium bond length (3.8A). Calculate the force on the third atom
