ul("Calculate") the frequency in s^(-1) of infrated photons that can be absorbed by HD molecule. (If you have been unable to calculate the value for epsilon_(HD) then use 8.000xx10^(-20) the calculation) The allowed electronic energies of H atom of H atom are given by the expression: E=-R_(H)/n^(2), n=1, 2, .... where R_(H)=13.5984 eV and 1 eV=1.602xx10^(-19) J The total energy of H_(2) molecules in its ground state is -31.675 eV, relative to the same refrence as that of hydrogen atom. |

Answer» `DeltaE=E_(v1)-E_(V0)=(3/2-1/2)epsilon_(HD)=epsilon_(HD)` `hv=epsilon_(HD)rArr v=epsilon_(HD)/h` From PART `3.1 :` `epsilon_(HD)=7.5724xx10^(-20) J` Thus : `v=(7.5724xx10^(-20) J)/(6.6261xx10^(-34) J s)=1.1428xx10^(-14) s` |
