开发了一个引导探究实验室来分析氢原子光谱的巴尔默系列。用自制台式分光光度计记录氢的发射光谱。通过绘制图表和反复试验的方法，学生发现了里德伯公式中呈现的线性关系，并将其与氢原子的玻尔模型联系起来。讨论了自制分光光度计的构造、数据分析以及实验数据与已发表数据的比较。还讨论了确定氘的里德伯常数作为该实验室的可能扩展的可能性。
A guided-inquiry lab was developed to analyze the Balmer series of the hydrogen atomic spectrum. The emission spectrum of hydrogen was recorded with a homemade benchtop spectrophotometer. By drawing graphs and a trial-and-error approach, students discover the linear relationship presented in the Rydberg formula and connect it with the Bohr model of the hydrogen atom. The construction of the homemade spectrophotometer, the analysis of data, and the comparison between experimental and published data are discussed. The possibility of determining the Rydberg constant for deuterium as a possible extension of this lab is also discussed.
