We report photoassociation spectroscopy of ultracold $^{86}$Sr atoms near theintercombination line and provide theoretical models to describe the obtainedbound state energies. We show that using only the molecular states correlatingwith the $^1S_0$$+$$^3P_1$ asymptote is insufficient to provide a mass scaledtheoretical model that would reproduce the bound state energies for allisotopes investigated to date: $^{84}$Sr, $^{86}$Sr and $^{88}$Sr. We attributethat to the recently discovered avoided crossing between the $^1S_0$$+$$^3P_1$$0_u^+$ ($^3\Pi_u$) and $^1S_0$$+$$^1D_2$ $0_u^+$ ($^1\Sigma^+_u$) potentialcurves at short range and we build a mass scaled interaction model thatquantitatively reproduces the available $0_u^+$ and $1_u$ bound state energiesfor the three stable bosonic isotopes. We also provide isotope-specifictwo-channel models that incorporate the rotational (Coriolis) mixing betweenthe $0_u^+$ and $1_u$ curves which, while not mass scaled, are capable ofquantitatively describing the vibrational splittings observed in experiment. Wefind that the use of state-of-the-art ab initio potential curves significantlyimproves the quantitative description of the Coriolis mixing between the two -8GHz bound states in $^{88}$Sr over the previously used model potentials. Weshow that one of the recently reported energy levels in $^{84}$Sr does notfollow the long range bound state series and theorize on the possible causes.Finally, we give the Coriolis mixing angles and linear Zeeman coefficients forall of the photoassociation lines. The long range van der Waals coefficients$C_6(0_u^+)=3868(50)$~a.u. and $C_6(1_u)=4085(50)$~a.u. are reported.
