Scientific paper

The equivalent width calculations for the fundamental vibration rotation band lines of HeH(+) have been carried out for a non-DA white dwarf model with an effective temperature of 12,000 K. Both P and R branch lines with rotational quantum numbers J = 3 to 18 were included in the calculations. A search for these lines in helium rich white dwarfs is suggested.
