The splitting of spectral lines by a magnetic field is called the zeeman effect after the Dutch physicist Pieter Zeeman. The Zeeman effect is a vivid confirmation of of space quantization. Magnetic quantum number 'm' was introduced during the study of zeeman effect. 'm' can have the (2l+1) values (-l,0,+l). Magnetic quantum number represents the orientation of atomic orbitals in three-dimensional space. the normal zeeman effect consists of the splitting of a spectral line of frequency v_(0) into three components i.e., v_(1)=v_(0)-(e)/(4pim)B,v_(2)=v_(0),V_(3)=v_(0)+(e)/(4pim)B Here, B is magnetic field. Q. A d-subshell in an atom in the presence and absence of magnetic field is:
