光谱线是均匀连续光谱中的暗线或亮线，这是由于与附近频率相比在窄频率范围内光的发射或吸收。光谱线通常用于从其特征谱线鉴定原子和分子。因为由于电子云中的电子在环绕原子核时，只能受限拥有一些特定的能量，所以一旦电子能量有变化，此能量差就会产生该原子特有的光子，这就是谱线的由来。

每一种样式代表一种不同的化学元素，所以光谱线的不同集合或模式意味着这颗恒星有不同的化学成分。
Each pattern stands for a distinct chemical element, and so different sets or patterns of spectral lines mean that the star has a different chemical composition.

First there was the observation by Michelson who back in the late 1880s had done very precise interferal metric measurements of the hydrogen lines and had observed that the 656 nanometer line 3 associated with the transition of n equals 3 to n equals 2 was, in fact, a doublet.
首先是麦克逊,在1880年底的观察,他以公制单位对氢原子的光谱线,作了准确的，无其他因素干扰的，测量,发现当n值由3变为2时,会同时得到波长为656纳米的谱线3,实际上是有两条线。
