Sorry! Your simulation took too long. Reduce your simulation range or increase Δν.
Sorry! We reduced your resolution νstep to reduce compute time.
Every mole fraction must be less than 1! See "How it works" for an explanation of how mixtures are handled.
Mole fractions should be less than 1! In the LineSurvey, mole fractions are used to scale linestrength.
You're simulating a big range. For surveys, we recommend using the LineSurvey tool.
Your wavelength is quite short! Check the HITRAN documentation to see if visible/UV lines are included for this species.
Not all of your lines were plotted, sorry! Either reduce your simulation window or increase the Linestrength cutoff.
Your simulation range is too big, Sorry! We can only simulate 5000 cm-1 at a time with HITRAN.
Sorry! Your minimum linestrength must be greater than 1e-10!
It looks like you're simulating N2 with a relatively short pathlength. N2 is only weakly infrared active. Make sure you double check how mixtures are calculated, described in the How It Works.
Some lines for in your simulation have estimated line strengths. The NIST database does not have all of the Einstein A coefficients for these species in this spectral window, so we estimate line strengths using A=107 s-1. Please use the LineSurvey tool to explore in more detail.
HITEMP CO2 and H2O have a lot of lines! Please reduce your simulation window to less than 1000 cm-1. Web browsers have a hard time plotting that much data, and the database queries can take a while.
Wavelength Search Details
The Wavelength Search Enginebeta presents hardware and optics relevant to your wavelength.
As spectroscopists and scientists, we know that the photonics industry is fragmented and disjointed. We're aiming to improve your ability to accomplish your science and engineering goals by making your hardware search easy and intuitive.
If your favorite vendor doesn't show up in our search, please let us know, and we'll reach out to include them in our catalog!

SpectraPlot Ltd. is a 501(c)(3) non-profit organization. Our mission is twofold: 1) to strengthen the spectroscopy community and 2) to organize the photonics industry's information for spectroscopists.
To achieve these goals, Spectraplot offers integrated search tools for wavelength-dependent data (including spectral simulators and hardware listings) organized around function and use. These tools are aimed to accelerate spectroscopic and optical engineering and to remove transactional friction in the photonics industry. We hope you will join us in this mission by simply using our tools. If you are a vendor interested in either supporting SpectraPlot or including your catalogue on the site, get in touch with us at email@example.com. A couple FAQs are addressed below.
Q. But really, what is SpectraPlot?
A. SpectraPlot is a free, openly-available tool for scientists and engineers to simulate spectroscopic data and find the hardware you need to put spectroscopy into practice. SpectraPlot is an ongoing project, and we'll continue to add tools, databases, and calculators that benefit the science and engineering communities that advance and leverage spectroscopy.
