We explore and characterize the behavior of ensembles of nitrogen vacancy qubits under transverse magnetic fields. In this regime, we predict and experimentally observe crossings and anti-crossings of the hyperfine splitting levels which occur at an order of magnitude less field than the axially-applied 510 G and 1000 G level anti-crossing characteristic of the excited and ground states. This system is a good candidate for electric field sensing, temperature sensing, and quantum memories in this novel transverse field regime. In addition, we quantify both advantages and limitations of addressing distributed ensembles of nitrogen vacancies in a bulk diamond under transverse magnetic field.
