Figure 6: Product vibrational branching ratio as a function of collision energy.
This is defined as the ratio between the integral cross-section (ICS(ν′=1)) and ICS(ν′=0) for the C(1D)+D2(ν=0, j=0)→CD(ν′)+D reaction. Accurate quantum dynamics (QD) results calculated on our 
and 
PESs are compared with the available crossed-beam experimental value25, along with our QD results calculated on the RKHS PES and the roughly estimated lower limit of the QD value on the RKHS (
) and BJHL (
) PESs. The corresponding contributions of our 
and 
PESs are also shown, respectively.
