Results and discussion

Results:
Using molecular simulation and a force field calculation the lowest energy conformation in 3D appears below. The distance between the two terminal methyl hydrogens are about 18.17 A, and we must add twice the Van der walls radius of H to this ( 0.5 A x 2) to get a final Dmax number of 19.17 Å.

Applicant's summary and conclusion

Conclusions:
Dmax of the substance is 19.17 Å.
