^15^NH_2_ amidogen radical rotational spectrum

The determination of isotopic ratios in interstellar molecules is a powerful probe of chemical routes leading to their formation. In particular the ^14^N/^15^N abundance ratio...星际分子（interstellar molecules）的同位素比值（isotopic ratios）测定，是揭示其形成过程中化学路径的有力探测手段。具体而言，¹⁴N/¹⁵N丰度比值……
