Abstract
A molecular beam -optical double resonance experiment was performed on 87 in its naturally occurring abundance ration. Numereous magnetic dipole allowed transitions between $\rho$-doubles in the $X^{2}\Sigma{^{+}}$ 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 quadropole interactions arising from the $^{87} Sr(1 = 9/2)$ and $^{9}F(1=1/2)$ nuclei. The extracted spectroscopic hyperfine parameters were interpreted in terms of a simple molecular orbital picture for the electronic nature of the $X^{2}\Sigma^{+}$ state. A comaprison is made to previous results for the more aboundant 86 SrF and 88 SrF isotopic forms
