The nuclear structure of [Formula Presented] has been studied by the [Formula Presented] reaction at 70 MeV. Thirteen levels were identified in [Formula Presented] and angular distributions have been measured for the first time for this reaction. Based on the observed transferred angular momentum dependence of the angular distributions, a spin-parity assignment has been made for several states in [Formula Presented] With the inclusion of the data on [Formula Presented] quartet analog states have been completed for six levels in the [Formula Presented] isobar system. The level shifts in these [Formula Presented] nuclei are analyzed in terms of the isobaric multiplet mass equation (IMME). The results of such an analysis show a slight linear dependence of the [Formula Presented] and [Formula Presented] coefficients of the equation on the excitation energy. The coefficients for the positive parity states seem to follow a different systematics than the negative parity states, suggesting that these parity-dependent level shifts are reflecting the structure change. These coefficients of the IMME are discussed.
