Abstract: | The24MgH+ (A
1 + –X
1 +) molecular lines have been identified in the photospheric spectrum. The rotational excitation temperature determined from the analysis of molecular line intensities of24MgH+ is found to be of the order of 4850 K which corresponds to the photospheric temperature of the Sun. The CNDO/2 dipole moments of24MgH+ for internuclear distance range: (1.3–2.1) Å in theX
1 + state can be approximated byM(R)=4.92+1.33R. Estimations for the spontaneous emission Einstein coefficients (A
v v
) and the absorption oscillator strengths (f
v v
) for the (1, 0), (2, 0), and (2, 1) transitions in theX
1 + state of the24MgH+ ion are also made.Work partially supported by the CNPq, Brasilia under contract number 30.4076/77. |
