Which element has 77 protons in its nucleus?
Xenon. Take the atomic mass of 131 and subtract it's protons 54, to get 77 neutrons.
How does IR gas analyzers work?
IR gas analyzers work by measuring the absorption of infrared light by different gases. Each gas absorbs infrared light at specific wavelengths, allowing the analyzer to identify and quantify the gases present in a sample. The amount of light absorbed is proportional to the concentration of the gas, which is then used to calculate the gas concentration in the sample.
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.
How does open path line of sight IR gas detector works?
Open path line of sight IR gas detectors work by emitting a beam of infrared light across an area, and then measuring the amount of light that is absorbed by gases in the path of the beam. When a gas is present in the path, it absorbs some of the infrared light, causing a decrease in the intensity of the beam. This decrease is detected by the sensor, which triggers an alarm to indicate the presence of the gas.
Use of kbr in ir spectroscopy?
Potassium bromide (KBr) is commonly used in infrared (IR) spectroscopy as a method to prepare solid samples for analysis. The sample is mixed with KBr and compressed into a pellet, which allows for better handling and analysis. KBr has a wide transmission range in the IR spectrum and is transparent to infrared radiation, making it a suitable medium for the sample to be measured.
Which is the best preparation for IR spectroscopy solid liquid or gas?
liquid
How are IR rays produced in transmitter circuit of IR alarm?
when an electron drops from a higher energy state to a lower it emits a fixed frequency photon Gallium Arsenic Silicon Carbon have bright lines in a band of infrared can be varied colors depending on proportions this is monochromatic IR if you put parallel mirrors on either side of the the activated atoms you get a laser co2 gas laser ... Led Solid laser although IR is produced by burning sugar in a body and digital cameras can see that too

Why chloroform uses in liquid ir spectroscopy?
Chloroform is commonly used as a solvent in liquid infrared (IR) spectroscopy because it is transparent in the mid-infrared range, which allows the IR radiation to pass through without interference. It also has good solvating properties, making it useful for dissolving a wide range of organic compounds for analysis. Additionally, chloroform has strong absorption peaks in the IR spectrum, which can serve as reference points for calibrating the instrument.

Which kind of rocket engines are used on the space shuttle?
liquid because ir never runs out <3
What is a active gas?
Absorption of energy from IR radiation can only occur when the wavelength of radiation and the wavelength of the bond vibration match. If a molecule has symmetry...for example no dipole, we say it is IR inactive. CO2 has no dipole....this would be an IR inactive gas...Cl2 as well. A gas that has a dipole would be IR active. Propene would be a nice example of an IR active gas.It possesses a dipole. One would see a signal around 1650.A:CO2 has no permanent dipole. However, when CO2 undergoes a bending vibration, its dipole moment changes from zero to some non-zero value. This vibration produces a change in dipole moment and is therefore IR active.

Where can I purchase a new IR cable?
There are different IR Cables but after some research, there are two solid online resources for a new IR cable purchase. You can order replacement IR control cables from www3.tivo.com/store/accessories.do. There are also IR cables of different types offered on Ebay.com, some of these offers are new and some are used. You can buy a new IR cable just about anyplace that sells electronic items. You can check at your local Walmart, Target and Rdaio Shack.
Why organic liquid must be dried before IR spectrum is run?
Organic liquids must be dried before running an IR spectrum to remove any water or solvents present in the sample. Water and solvent peaks may overlap with the peaks of interest in the IR spectrum, interfering with the analysis and leading to inaccurate results. Additionally, the presence of water or solvents can affect the baseline of the spectrum, making it difficult to interpret the data.
