A molecular beam rf--optical double resonance experiment was performed on {sup 87}SrF in its naturally occurring abundance ratio. The natural occurring abundances of the strontium isotopes are {sup 86}Sr (9.8%), {sup 87}Sr(7.02%) and {sup 88}Sr (82.5%). Numerous magnetic dipole allowed transitions between {rho}-doublets in the {ital X} {sup 2}{Sigma}{sup +} state were measured to an accuracy of 3 kHz. The observed spectra were analyzed in terms of an effective Hamiltonian which includes the magnetic hyperfine and electric quadrupole interactions arising from the {sup 87} Sr ({ital I}=9/2) and {sup 19}F ({ital I}=1/2) nuclei. The extracted spectroscopic hyperfine parameters were interpreted in terms of a simple molecular orbital picture for the electronic nature of the {ital X} {sup 2}{Sigma}{sup +} state. A comparison is made to previous results for the more abundant {sup 86}SrF and {sup 88}SrF isotopic forms.
