4. According to MO theory, the lowest energy wavefunctions for H, are: ei +1) = 1 12 + 2aby'7 (41s(a), + +15(b),) 1 ez W+(2) [2 + 2ab]*2 (U1s(a)2 +41(b)2) The symmetric spatial functions are: Wspace (sym) = 2+(1)4+(2) [v+(1)y_(2) +-(1)4+(2)] -(1)-(2) a. Write Yspace (anti). b. Show 4+ (1)4+(2) is symmetric to the interchange of: i. electrons 1 and 2 ii. protons a and b C. Show V+(1)+(2) is normalized. d. Show 4+(1)y+(2) is orthogonal to Y-(1)y_(2)
