Synopsis

Discover a meticulous, in-progress catalog of the solar spectrum you can trust to guide your lab work.

This volume presents the early, carefully measured table of solar spectral lines by Henry A. Rowland. It explains how wavelengths were measured from photographs of the solar spectrum, with values given in air at 20°C and 76 cm of mercury. The work emphasizes the scale and precision used, noting the broad range of line intensities and the plan to expand and correct the table over time. This edition captures the method and scope of an ongoing project, inviting researchers to use the data while acknowledging potential refinements ahead.

What you’ll experience
  • A detailed table of solar spectrum wave-lengths and accompanying notes on line identifications and intensity
  • Explanations of the measurement approach, standards, and the meaning of symbols used in the table
  • Context on how the data were gathered, verified, and prepared for future updates
  • Insight into the scale of intensity used for solar lines, including strong lines like H and K
Ideal for readers of historical scientific literature, spectroscopy students, and researchers who value original measurement work and its evolving nature.
