b H22 transfers from N19 to O1; H22-O2 distance is 1.000 Å and ρ(N19-H22)=0.04895 c H22 transfers from N19 to O1; H22-O2 distance is 1.002 Å and ρ(N19-H22)=0.04922 0.00000 0.00000 0.00000 0.00095 0.00000 0.01157 a n/a means "not applicable": one or both of the atoms were not present. NC means ρ value was "not calculated" and is expected to be greater than 0.1. A value of ρ=0 indicates that there is no density between these atoms, and hence there is no bond between these atoms. b H6 transfers from O4 to O15; H36 transfers from O15 to O16; O16-H36 distance is 1.056 Å; O15-H36 distance is 1.471 Å c H6 transfers from O4 to O15; H36 transfers from O15 to O16; distance between O16-H36 is 1.047 Å; distance between O15-H36 is 1.494 Å d H6 transferred from O4 to O15; H36 transferred from O15 to O16; H6-O15 distance is 0.993 Å; O4-H6 distance is 1.704 Å e H6 has transferred from O4 to O15; distance between O15-H6 is 0.992 Å; distance between O4-H6 is 1.693 Å f H6 has transferred from O4 to O15; H37 has transferred from O15 to N26; O15-H6 distance is 0.969; O4-H6 distance is 2.017; N26-H37 distance is 1.019; O15-H37 distance is 2.484 O4-H27 0.00000 0.00000 0.00520 0.03091 O4-H10 0.02554 n/a 0.00000 0.00000 a n/a means "not applicable": one or both of the atoms were not present.
