QM7-X molecule 7070 has an optimized reference geometry (opt) and a paired displaced geometry (d1). Using the attached official 3-component dipole vector (vDIP) at each geometry, compute the dipole moment magnitude at opt and at d1, then report the signed change (d1 minus opt) in e.Ang to four decimal places. Does the total dipole moment magnitude increase or decrease under this displacement?

opt and d1 are the same paired QM7-X structures attached as S0016 and S0017. The official per-geometry dipole fields (units e.Ang, i.e. elementary charge times angstrom) are:
opt: DIP (scalar) = 0.91735; vDIP (x,y,z) = [0.751731, 0.525751, 0.004184]
d1: DIP (scalar) = 0.812457; vDIP (x,y,z) = [0.670446, 0.453557, -0.069822]
Compute the magnitude of each vDIP vector yourself from its three components; do not simply copy the scalar DIP field without checking it (the two should agree closely but the magnitude you report must come from vDIP).
