Why this conversion matters in chemistry
Microwave rotational spectroscopy probes gas-phase molecular rotations in the 2–40 GHz range — exactly the regime where the rotational energy spacings of small molecules sit. The J = 1 ← 0 transition of OCS, for instance, lands at 12.163 GHz, which corresponds to a rotational constant B of about 6.081 GHz. Inside the instrument, that same frequency is 1.2163 × 10¹⁰ Hz, the value the time-domain signal processor actually sees. Multiplying by 10⁹ is the conversion that bridges what gets published in a paper and what the data acquisition pipeline actually handles.
