We theoretically study the dependence of photoelectron angular distribution on laser polarization direction in nitrogen molecules.The approach is based on the time-dependent density functional theory at the level of local density approximation complemented by self-interaction correction.It is found that photoelectron emission in one photon regime could be considered as a probing tool for the main character of different types of molecular orbitals(a or π).The pattern of emitted photoelectrons strongly depends on the polarized angle of the laser,for a orbital,the number of photoelectron decreases with increasing the polarized angle,while for ir orbital,it has the inverse relation to the polarized angle,which reveals the multi-electron effect in molecules.On the other hand,concerning the total photoelectron emission,one should take into account a few occupied orbitals instead of only the outmost one.
