Вычисление атомных орбиталей водорода
В этом практикуме необходимо, опираясь на уравнение, построить электронную плотность в одноэлектронном атоме и сравнить с выдачей известных программ.
Импортируем модули и функцию Андрея Демкива.
import numpy
import scipy.special
import scipy.misc
import npy2cube
Задаем волновую функцию:
def w(n,l,m,d):
x,y,z = numpy.mgrid[-d:d:30j,-d:d:30j,-d:d:30j]
r = lambda x,y,z: numpy.sqrt(x**2+y**2+z**2)
theta = lambda x,y,z: numpy.arccos(z/r(x,y,z))
phi = lambda x,y,z: numpy.arctan(y/x)
a0 = 1.
R = lambda r,n,l: (2*r/n/a0)**l * numpy.exp(-r/n/a0) * scipy.special.genlaguerre(n-l-1,2*l+1)(2*r/n/a0)
WF = lambda r,theta,phi,n,l,m: R(r,n,l) * scipy.special.sph_harm(m,l,phi,theta)
absWF = lambda r,theta,phi,n,l,m: numpy.absolute(WF(r,theta,phi,n,l,m))**2
return WF(r(x,y,z),theta(x,y,z),phi(x,y,z),n,l,m)
# определим шаг grid при заданном диапозоне от -d до d
d = 50
step = float(d/30)
# зададим цикл по перебору квантовых чисел
for n in range(0,4):
for l in range(0,n):
for m in range(0,l+1,1):
grid = w(n, l, m, d)
name='grid3/%s-%s-%s' % (n,l,m)
# для сохранения нужно задать координаты старта grid и шаг по каждому направлению
npy2cube.npy2cube(grid,(-d, -d, -d),(step, step, step),name+'.cube')
Получили такие изображения орбиталей. Если уменьшить параметр d до 50, становится видна и 1s орбиталь.
Теперь попробуем рассчитать орбитали в программе ORCA. Создаем файл h3.inp для orca и запускаем ее:
%%bash
export PATH=${PATH}:/tmp
orca h3.inp

Программе нужно дать на вход два параметра орбиталей. Что значат эти параметры, было не ясно. В мануале программы я нашла информацию, что, видимо, первое число - это число орбиталей, а второе - некий оператор, который для UHF может принимать значения 0 и 1 в зависимости от спина. Как эти два параметра связаны с квантовыми числами, выяснить не удалось :(
Я варьировала эти параметры, и в итоге, орбитали получились для (0,0) - (4,0) и для (0,1) - (4,1). Для остальных значений программа выдавала ошибки ERROR CODE RETURNED FROM PLOT PROGRAM или "Invalid MO requested for plot (<0 or >=DIM)".
Формы орбиталей (0,0) - (4,0) сохранились в файлах "H-0.cube" ... "H-4.cube". Их загрузили в PyMOL через функцию volume (так же, как и предыдущие орбитали):
H-0 и H-1 это s-орбитали, остальные - p с разным числом m. Получается, что не вышло построить d-орбитали.
В итоге, при построении орбиталей с помощью orca орбитали более "гладкие", чем при построении вручную. Для сравнения нужно знать, какие орбитали orca каким уровням соответствуют.
