Nujol is a mineral oil derived from petroleum, primarily composed of hydrocarbons. Its structure consists of long chains of aliphatic hydrocarbons, typically ranging from C15 to C40, which contribute to its viscous nature. The presence of various saturated and unsaturated hydrocarbons gives Nujol its lubricating properties, making it useful in various applications, including as a medium for infrared spectroscopy. Additionally, Nujol has a relatively low volatility due to its high molecular weight.
What else can I help you with?
Why in some cases nujol technique is used In IR spectroscopy and in some other cases rest of techniques Is there any specific reason which technique to use and when?
The Nujol technique is used in IR spectroscopy when analyzing samples that are solids or semi-solids. This technique involves mixing the sample with Nujol, a heavy oil, to create a mull which allows for better interaction with infrared radiation. Other techniques, such as ATR (Attenuated Total Reflection) or transmission, are often used for liquid or gas samples as they provide different advantages in terms of sensitivity and ease of use based on the physical form of the sample. The choice of technique therefore depends on the nature of the sample being analyzed.
Why is nujol used to prepare samples for infra red spectroscopy?
Nujol, a mineral oil, is used in infrared spectroscopy to prepare samples because it serves as a non-volatile, inert medium that does not interfere with the infrared absorption spectra of the sample. It helps in forming a paste or film, allowing for even distribution of solid samples, enhancing the clarity of the spectral data. Additionally, Nujol has a low refractive index, which minimizes scattering effects and enables better transmission of infrared light.
Why is nujol used?
to provide a protective layer or coating for the sample if the sample is a reactive sample. forming a protective layer or coating would prevent decomposition of the sample during the IR reading process.
What is inner structure?
An Internal Structure is the way an organism looks on the outside and an External Structure is the looks on the outside.

How much is a nujol bottle worth?
The value of a Nujol bottle can vary significantly based on factors such as age, condition, and rarity. Generally, vintage or collectible Nujol bottles can range from $10 to $100 or more, while newer or common versions may be worth less. Collectors often consider the bottle's design and any unique features when determining its worth. For an accurate valuation, consulting a collectibles expert or appraiser is recommended.
