摘要
用分光计采用最小偏向角法,测出汞灯、氢灯和氦-氖激光器发出的已知谱线的波长所对应的折射率,利用Origin8.0软件,拟合出色散曲线,得到色散公式.再通过测量钠灯各谱线的波长及确定其所属线系来测定里德堡常数.测量结果相对误差为2.95%,实现了使用普通常规仪器测量里德堡常数.
Making good use of Origin8.0 software,the dipersion curve and dispersion formula of prism have been given based on the method of minimum angle of deflection using mercury lamp,hydrogen lamp helium-neon laser.The Rydberg constant is obtained by virtue of measuring wave length of natrium spectral line and make sure their categories using spectrometer and natrium lamp.Spectroscopy is constantly determined by general instruments with 2.95% error.
