A Slater determinant is an anti-symmetrized wave function

Electronic wave function should be represented by Slater determinants           

A Slater determinant always corresponds to a particular spin state

A Slater determinant obeys the Pauli Exclusion Principle

A = CH₂I₂, Zn—Cu; B = Me₃S⁺I^–, NaH

A = CH₂I₂, Zn—Cu; B = Me₃S⁺ (O) I^–, NaH

A = Me₃S⁺I^–, NaH; B = Me₃S⁺ (O) I^–, NaH

A = Me₃S⁺ (O) I^–, NaH; B = CH₂I₂, Zn—Cu

It forms a base centered cubic unit cell                   

It forms a face centered cubic unit cell           

Its coordination number is 8

Chemical compounds are separated by heating them to a temperature at which one or more fractions of the mixture will vaporize           

Generally the component parts have boiling points that differ by less than 25 °C (77 °F) from each other under a pressure of one atmosphere.           

If the difference in boiling points is greater than 25 °C, a simple distillation is typically used.
