首次发现了原子钒的四个新的精细结构能级。实验采用激光诱导荧光光谱法和光电光谱法，分别使用波长为750 ~ 850 nm和590 ~ 650 nm的可调谐连续波激光器。这些新的能级都位于42 400到49 940 cm−1的能量范围内，每个能级都是通过两次或两次以上观察到的涉及先前已知能级的跃迁实验证实的。用傅立叶变换光谱学测得的谱线得到了精确的能级值。通过分析所研究的光谱线的超精细结构，得到了新能级的总角动量量子数J的值。确定了所有新能级的磁偶极子超精细结构常数A。此外，对文献中已知的一个能级的磁偶极子超精细结构常数A进行了修正。
Four new fine structure energy levels of atomic vanadium have been discovered for the first time. Experiments were carried out with laser-induced fluorescence spectroscopy and optogalvanic spectroscopy using tunable continuous wave lasers in the wavelength ranges between 750 nm and 850 nm and between 590 nm and 650 nm, respectively. The new levels, all lying in the 42 400 to 49 940 cm− 1 energy range, were each experimentally confirmed by two or more observed transitions involving previously known energy levels. Accurate energy level values were found using lines measured by Fourier transform spectroscopy. The values for the total angular momentum quantum numbers J of the new levels were found by the analysis of the hyperfine structure of the spectral lines investigated. Magnetic dipole hyperfine structure constants A for all new levels were determined. Additionally, for one previously known energy level the magnetic dipole hyperfine structure constant A from the literature was corrected.
