This quantum number is designated by the symbol m To explain splitting of a single spectral line into a number of closely spaced lines in the presence of magnetic field Zeeman effect Linde proposed that electron producing a single line has several possible space orientations for the same angular momentum vector in a magnetic field i e under the influence of magnetic field each subshell is further sub divided into orbitals Magnetic quantum number describes the orientation or distribution of electron cloud For each value of l the magnetic quantum number m may assume all integral values from to including zero i e total 27 1 values
