Unformatted text preview: Name: Chem 5314 test #2 solutions out of 30 marks I want complete, detailed answers to the questions. Show all your work to get full credit. Data: Z  e x 2 = (1) Z  x 2 e x 2 = 2 3 / 2 (2) The Schr odinger time dependent equation in one dimension is i ~ ( x,t ) t = ~ 2 2 m 2 ( x,t ) x 2 + V ( x ) ( x,t ) (3) The Schr odinger time independent equation in one dimension is ~ 2 2 m d 2 n ( x ) dx 2 + V ( x ) n ( x ) = E n n ( x ) (4) The particle in a one dimensional box (of size L ) energy levels are E n = n 2 2 ~ 2 2 mL 2 n = 1 , 2 , 3 ,... (5) and the wavefunctions for the particle in a one dimensional box are ( x ) = p 2 /L sin( nx/L ) x (0 ,L ) (6) The particle in a threedimensional box (of side lengths a , b , c ) energy levels are E = 2 ~ 2 2 m n 2 x a 2 + n 2 y b 2 + n 2 z c 2 n x , n y , n z = 1 , 2 , 3 ,... (7) ground state wavefunction of the harmonic oscillator: ( x ) = 2 1 / 4 e x 2 (8) with = 2 ~ and = ( k/ ) 1 / 2 (9) 1 where k is the force constant and is the reduced mass. reduced mass formula: = m 1 m 2 / ( m 1 + m 2 ) energy levels of the harmonic oscillator: E n = ( n + 1 / 2) ~ , n = 0, 1, 2, ......
