www.drugfuture.comlight so that the transmitted light emerges at a measurableson, the D-line of the sodium lamp at the visible wavelength angle to the plane of the incident light. This property is of 589 nm was most often employed. Specific rotation de-characteristic of some crystals and of many pharmaceutical termined at the D-line is expressed by the symbol:

Once the arc tube reaches its running temperature, the sodium dissociates from the iodine, which adds orange and red to the lamp’s spectrum from the sodium D line as the metal ionizes. As a result, metal halide lamps produce an intense white light and have high luminous efficacy at
DIETARY Cut Down - Health
health.govSodium is a mineral, and most of the sodium in our foods comes from salt. We all need a little sodium to stay healthy. Eating too much sodium can lead to high blood pressure (hypertension). High blood pressure can raise your risk of having a heart attack or stroke.
Sodium Atomic Emission Spectrum - University of California ...
www.chem.uci.eduSodium Atomic Emission Spectrum The sodium spectrum is dominated by the bright doublet known as the Sodium D-lines at 588.9950 and 589.5924 nanometers. From the energy level diagram it can be seen that these lines are emitted in a transition from the 3p to the 3s levels. The line at 589.0 has twice the intensity of the line at 589.6 nm.
