The discussion centers on locating the spectral data for various elements, specifically the He II spectrum, as well as those for beryllium (Be) and boron (B). A recommended resource is the University of Oregon's online laboratory, accessible at http://jersey.uoregon.edu/vlab/elements/Elements.html, which provides comprehensive spectral information. The suggestion to utilize search engines for such inquiries is also noted as a practical approach for future reference.
