A low‐noise Raman signal of water at 3300 cm −1 was detected using a blue (465 nm) light‐emitting diode (LED) with an output power of 0.5 W. The linewidth of the LED emission spectrum (800 cm −1 ) was larger than the intrinsic width of the detected Raman feature (400 cm −1 ). Nevertheless, the comparison of the Raman spectra from distilled and potable water demonstrated that this novel technique is applicable to the normalization of fluorescence signals in water and water‐based solutions.
