Hydrogen cyanide is a tri-atomic linear molecule. In
units of atomic mass units u, the masses of the atoms are: H = lu,
C = 12u, N = 14u. In units of angstroms A, the bond lengths are:
H-C = 1.06A, C-N = 1.16A. How far from the hydrogen atom is the
molecule’s center-of-mass?

Q10M.9 Consider an HCl molecule. The hydrogen atom irn this molecule has a mass we can look up (see the inside front cover), and the chlorine mass is enough larger that we can (to a first degree of approximation) consider it to be fixed. The bond between these atoms has a local minimum .13 nm, and for "small oscillations" around that minimum, the bond's potential energy can be modeled as a harmonic oscillator potential energy function. Suppose we find that...
