Dihydrogen in Vycor, nickel II phosphate and a zinc complex

3 Dihydrogen in Vycor, nickel(II) phosphate and a zinc complex 

The fi S spectra of dihydrogen in these materials provide further examples of the utility of INS for studying dihydrogen binding in micro-or nanoporous materials. 

The rotational barrier associated with zinc was 1.67 kJ mol and with BDC 1 kJ mol, higher than single-walled carbon nanotubes (0.105 kJ mof ). The width of the rotational band (4 cm ) was much less than for carbon (20 cm ) showing a lower dihydrogen mobility and hence stronger binding in [Zii4(BDC)30] than carbon.
