| Jun 18, 2019 at 21:01 | comment | added | Andrew | The paper you linked with the reference to quantum mechanical calculations appears to be instead a description of a crystal structure doped with arginine. In that structure the C-N bonds are identical within error, and the guanidino group is described as planar, so all sp2 hybridized. | |
