if you see 'Error termination request processed by link 9999.' at the end of the log file, this means you have run out of steps (there is a default limit set).

Read the following before trying your adduct!

Important Optimisation in 'real life' is not always so easy as the carefully chosen example for the first part of the lab.

#MAKE THINGS SPIN IN JMOL HOW TO#

if you have a charged molecule ask a demonstrator how to enter charge in the calculation, it is very easy! (there is a box for charge in the methods tab).However if you have any doubts do ask the demonstrator or Prof Hunt. The following instructions are very brief because you know what is entailed.

repeat the process carried out on NH 3, BH 3 and H 3B-NH 3 but now apply this to your molecules.to make a molecule positive (or negative) on the Method tab set the Charge to +1 (or -1), the spin should now say 'Singlet', if it does not ask the demonstrator, because something has gone wrong!.D calculate + and NCl 3 and evaluate formation energy for +.C calculate + and PCl 3 and evaluate formation energy for +.B calculate + and NF 3 and evaluate formation energy for +.A calculate + and PF 3 and evaluate formation energy for +.you will have been assigned a group of two small molecules to investigate, and some key questions to answer, if you don't know what your group is contact the demonstrator or Prof.History: William Stein included Tachyon in Sage, then Tom Boothby, Josh Kantor and William Stein wrote some very preliminary 3d plotting functionality that relied entirely on tachyon, and could plot functions $z=f(x,y)$. I had once announced an intention to improve those for Sage, but upon closer inspection one finds that matplotlib is very 2d oriented and the 3d stuff just doesn't feel right at all. There are also some rudimentary 3d plotting capabilities in matplotlib. The show command also takes an aspect_ratio option e.g., sometimes aspect_ratio=1 is useful, in order to make sphere round, etc. Finally, you can place text in 3d using the text3d function.ДЄll 3d graphics objects have translate and rotate (and rotateX, rotateY, rotateZ) methods, which allow you to position the object or collection of objects anywhere you want.ДЄlso, you can set the color and opacity of any 3d object when you create it, as an optional parameter.ДЇinally, you can display a 3d scene G using either jmol (java) via G.show(), the Tachyon raytracer via G.show(viewer='tachyon'), or HTML5 canvas via G.show(viewer='canvas3d'). There are also numerous powerful tools for plotting data, functions, and surfaces in 3d, including cylindrical_plot3d, implicit_plot3d, list_plot3d, parametric_plot3d, plot3d, plot_vector_field3d, polygon3d, revolution_plot3d, spherical_plot3d, and implicit_plot3d. You can plot 1d arrows, lines, and curves in space using arrow3d, bezier3d, line3d. You can plot round objects using sphere and point3d. For example, you can draw platonic solids using tetrahedron, cube, octahedron, dodecahedron, icosahedron. There are many 3d graphics primitives in Sage. In Sage, just as with 2d graphics, you make 3d graphics by creating various primitives and combining them together using addition to create a 3d scene. Given any list of graphics objects, the animate command will make a single animated GIF file out of them. Sage: graphics_array(, ])Д«onus - you can animate graphics. Matrix_plot is another similar plotting function, which allows you to visualize a matrix.ДЇinally, there is a graphics_array function that lets you assemble several independent plots into a single big plot.

The result is a graphics object, which you can use just like any graphics object discussed above. It is probably the most used Sage plotting function. It is very useful especially for plotting functions of one variable. There are also a function just called 'plot' that makes a plot of a wide range of Sage objects.
