Homonuclear molecules have emerged as a crucial component in the pursuit of frequency standards, offering a promising avenue for the discovery of new physics phenomena that transcend the standard model. They also provide a unique approach to constraining variations in fundamental constants over time, thereby complementing the capabilities of atomic clocks. A notable challenge faced by molecular and single atomic quantum systems is the management of blackbody radiation (BBR), which introduces significant systematic errors and is challenging to regulate effectively. To address this issue, we perform ab initio quantum chemical calculations to accurately determine the potential energy curve and the polarizability tensor for the ground state of the N2+ molecular ion, one of the most promising candidates for searching for variation of me/mp and creating frequency standards. We then calculate the BBR shifts affecting the vibrational levels of the ground electronic 𝑋2⁢Σg+ state, marking a substantial contribution towards the precise experimental measurements.
