Quinine is a strongly fluorescent compound in dilute acid solution with two excitation wavelengths (250 and 350 nm) and a fluorescence emission at 450 nm.
Is tonic water fluorescent?
The answer is surprisingly simple: Tonic water actually contains the chemical quinine, which fluoresces under certain light and makes tonic water glow.
Is quinine a sulphate fluorescent?
The fluorescence emission spectrum of Quinine sulfate dissolved in 0.5 M H2SO4. The excitation wavelength was 310nm. The quantum yield of this molecule is 0.546 (Eaton, 1988). This spectrum was collected by in the summer of 1995 using a Spex FluoroMax.
Does quinine glow under UV light?
Under an ultraviolet "black light," the quinine in tonic water makes the water fluoresce a brilliant, bright blue (even though only a relatively small amount of quinine is dissolved in the water).
Is quinine a luminescent?
Once frequently used to treat malaria, quinine is an alkaloid found in the bark of the cinchona tree. It is sometimes found in tonic water, and it also happens to be fluorescent. Under a black light, quinine will glow blue.

3 shows the fluorescence of the quinine in tonic water. Quinine is an alkaloid used to treat malaria. It is a strongly fluorescent compound in dilute solutions of H2SO4 (Φf=0.55). Quinine's excitation spectrum has absorption bands at 250 nm and 350 nm and its emission spectrum has a single emission band at 450 nm.
What is natural quinine?
Quinine is a bitter compound that comes from the bark of the cinchona tree. The tree is most commonly found in South America, Central America, the islands of the Caribbean, and parts of the western coast of Africa. Quinine was originally developed as a medicine to fight malaria.
Is UV and blacklight the same?
Strictly speaking, a black light is a kind of UV light. Black lights emit ultraviolet radiation (UV light). UV is radiation with a wavelength just shorter than that of violet light, which is the shortest wavelength of light in the visible part of the electromagnetic spectrum.
Where does quinine come from in tonic water?
Cinchona and malaria
The bitter flavouring of tonic water comes from an alkaloid called quinine which is extracted from the bark of the Andean fever tree (Cinchona spp.). The tree's remarkable curative properties were discovered as a fever remedy in South America in the early 17th century.
Is gin a fluorescent?
So, while gin itself isn't fluorescent, a G&T is the perfect glowing drink. There are lots of other tricks out there that can turn your drinks from dull to neon under the judgment of a blacklight, as well.
Is fluorescence a type of luminescence?
There are three main forms of luminescence at play: fluorescence, phosphorescence and chemiluminescence. Fluorescence and phosphorescence are two forms of photoluminescence. In photoluminescence, a substance's glow is triggered by light, in contrast to chemiluminescence, where the glow is caused by a chemical reaction.
Why is quinine diluted in sulfuric acid?
Quinine is a very strongly fluorescing compound, especially in dilute acid solution, and therefore very low concentrations can be detected. In dilute H2SO4, quinine has two analytically useful excitation wavelengths, 250 and 350nm.
Does tonic water glow in the dark without a black light?
Key Takeaways: Glow in the Dark Drinks
However, many safe liquids glow (fluoresce) under black or ultraviolet light. Of these, the brightest glow is produced by tonic water, which appears blue. Without a black light, drinks may be made to appear to glow using presentation tricks.
Does all Schweppes have quinine?
Tonic water in general and Schweppes tonic water, in particular, contains no more than 83 mg of quinine/liter. Schweppes quinine concentration is much less than the amount of quinine in the therapeutic dose of quinine tablets. Specifically, Schweppes quinine content is 67 mg/liter.
Is it OK to drink tonic water every day?
Even three glasses daily should be OK as long as you are not sensitive to quinine. Some susceptible people develop a dangerous blood disorder after even small doses of quinine. Symptoms of quinine toxicity include digestive upset, headache, ringing in the ears, visual disturbances, skin rash and arrhythmias.

What color is sperm under a blacklight?
Semen fluoresces blue between 300-450 nm, in the ultraviolet range. The invisible (to us) UV rays doesn't interfere with the fluorescence, so forensic experts can see the stains clearly.
Is purple light the same as UV light?
Purple LEDs are ultraviolet and they can be used to create a blacklight effect. Though you can make a brighter purple by mixing red and blue on an RGB LED, it won't have the same effect as the ultraviolet lights used in counterfeit bill detectors and for revealing security holograms on credit cards and driver licenses.
